The best poultry feeders for large flocks hold 50 to 100 lb of feed, keep that feed dry, and limit how much a bird can rake onto the ground. For most flocks of 20 birds and up, the OverEZ 50 lb gravity feeder is the best all-round choice, while the Grandpa’s 40 lb treadle is the one to buy when rats are the main problem.
That distinction matters more than it sounds. A feeder that suits a dozen backyard hens falls apart at 50, 100 or 200 birds: the hopper empties before breakfast is over, bully hens block every port, and spilled feed becomes a buffet for rodents. Most roundups online are written for flocks of six to fifteen, which is why so many keepers end up refilling a small feeder twice a day.
We spent time with all ten feeders in this guide, weighing capacity against port count, checking what happens in rain, and working out how many days of feed each one actually covers. The short version: capacity decides how often you make trips to the feed store, and pest protection decides how much of that feed you still own a month later. If you are still comparing basics, our general chicken feeder roundup covers the smaller backyard options first.

1. OverEZ 50 lb Gravity Feeder – Best Overall for Large Flocks
OverEZ Chicken Feeder – Holds 50 Pounds of Feed – Inside or Outside Hen Coop – Large Gravity Fed Automatic Poultry Dispenser – No Waste Rainproof Design
Capacity: 50 lb
Material: UV-resistant BPA-free plastic
Ports: 3
Weight: 5.4 lb
Pros
- 50 lb capacity cuts refills to once or twice a week
- Recessed channel and port overhang keep rain out
- Three ports let several birds eat at once
- Wide mouth lets you refill and clean at ground level
Cons
- Plastic body is less rigid than galvanized metal
- Only three feeding ports for a large flock
- Chewing damage is possible from determined pests
This is the feeder we come back to for most large flocks. It holds 50 lb of feed in a freestanding body that works equally well inside a coop or out in the run, and the whole unit weighs 5.4 lb, so you can tip it to refill rather than wrestling a full hopper off a shelf.
The port design is the reason waste stays low. Feed sits in a recessed channel under an overhanging port, so rain runs off the edge instead of down into the pile, and the angled feed path keeps pellets from being flung out by a bird working the port hard. The wide-mouth opening is large enough to scrub out by hand when the feed is low.
At 22.75 by 12.5 by 16.25 inches, it takes up very little run floor space, which matters when you are trying to fit feeders for a flock without choking off the birds’ walking room. Only three birds can eat at once, though, and that is the real limitation for large flocks.
Owners with bigger flocks tell us the same story: they end up running two of these rather than one, partly for capacity and partly so a dominant hen cannot claim the only port. The plastic itself is UV-protected, food-safe and recyclable, so it should outlast the cheaper non-UV domes that owners report yellowing and cracking after a season or two.
Who this feeder suits
This one works for anyone who wants a low-effort refill and does not have a serious rodent problem. It is a good match for a 20 to 30 bird flock on one unit, and a sensible pairing with a treadle for a 40 to 60 bird flock where you want backup on days the birds are timid.
Who should skip it
Skip it if rats are established on your property, or if you are running ducks, geese and turkeys alongside the chickens, since three ports will be contested. It is also the wrong tool for anyone who needs a feeder that can sit in the open with no rain hood and no cover overhead.
2. RentACoop 50 lb Metal Trough Feeder – Best Value Galvanized Option
RentACoop 50lb Gravity-Fed Metal Trough Feeder with Lid & Rain Cover
Capacity: 50 lb
Material: galvanized sheet metal
Dimensions: 22 by 14 by 10 in
Ports: open trough
Pros
- Heavy-duty galvanized metal with stainless screws
- 50 lb capacity suits large flocks
- Side window shows feed level at a glance
- Removable grate clips out for cleaning or larger birds
Cons
- Not suitable for chicks
- Open trough is more exposed than a port feeder
- Heavier and more assembly than plastic
If your flock includes ducks or waterfowl, or if you simply want metal that will still be there in five years, this is the one. The body is heavy-duty galvanized sheet metal fastened with stainless steel screws, which is the combination that resists both rust and the constant pecking at seams.
Two details make it stand out at scale. The built-in side window shows the feed level without opening the lid, so you can check three feeders on a walk in ten seconds, and the interior grate unclips upward for cleaning or can be removed entirely when ducks and geese need the headroom.
The magnetic lid and removable rain hood keep feed dry with the unit sitting in the open run, and the hood lifts off entirely for filling. At 22 by 14 by 10 inches the trough is wide, so a dozen birds can crowd the rail together rather than fighting over three ports.
The honest trade-off is exposure. An open trough lets birds rake feed outward, so waste runs higher than on a closed-port or treadle feeder, and rain protection depends on the hood being seated properly. It is also not a feeder for chicks at all.
Who this feeder suits
This fits mixed-species flocks and anyone on acreage where plastic has been chewed through. It is a strong second feeder for a 30 to 50 bird flock, especially where rain hits the run from one direction and the hood can be turned to cover it.
Who should skip it
Skip it in a rodent-heavy area, since the open trough gives mice and rats a low, straight path to the feed. Anyone whose birds roost heavily may also find droppings in the trough, which is one more reason to pair it with a roofed or guarded station.
3. Grandpa’s Feeders 40 lb Treadle – Best Rodent Proofing
Grandpas Feeders Automatic Chicken Feeder – 40 lbs No Waste Poultry Feeder, Rat Proof & Rodent Proof Treadle Chicken Feeder, Galvanized Steel with Lid, Feeds 6-12 Chickens up to 10 Days
Capacity: 40 lb
Material: galvanized steel
Weight: 23 lb
Mechanism: treadle lid
Pros
- Treadle lid closes when no bird is on the step
- Anti-flick grill and side guards cut waste
- Feeds 6 to 12 chickens for up to 10 days
- Full-coverage lid keeps out rain and snow
Cons
- Flat lid invites birds to roost on top
- Minimum bird weight excludes bantams and silkies
- Some flocks never learn to use the treadle
This is the answer to the single most common complaint we heard: rats reaching the feed no matter how high the feeder is hung. On r/BackYardChickens, owners describe hanging circular feeders at every height while rats still climb up to the buffet, and a treadle is the structural fix, because the opening only exists while a bird is standing on the step.
The anti-flick grill is the other half of the value. It stops birds grabbing a beakful and tossing feed over their shoulder, and the built-in side guards stop the side-pecking and injuries that show up on open feeders with a hungry flock. The manufacturer states one 40 lb fill feeds 6 to 12 chickens for up to 10 days.
Build quality is what you are paying for. The galvanized body has been sold since 2015, and owners report it staying watertight through heavy rain and wind, which matches what we saw. At 23 lb empty it stays put when birds push against it, and the full-coverage lid seals against wild birds and insects as well as rodents.
Two behaviors are worth planning around. The flat top is a roosting surface, so expect birds to sit on it and foul the lid, and the unit needs a minimum bird weight, which rules it out for bantams and silkies. Owners also report that some flocks never get over the quick-moving metal lid, which is the main reason training matters.
Who this feeder suits
Choose this for a 12 to 25 bird flock on rural acreage, anywhere rats are already in the coop. A flock of 30 to 40 birds will want two units, both positioned away from the perimeter fence and away from any low structure the rodents can jump from.
Who should skip it
Skip it for mixed-size flocks with bantams, for duck and goose flocks, and for anyone unwilling to spend the first week training. If you cannot check the flock daily for the first week, a port feeder will get you to the same result with less hassle.
4. Little Giant 40 lb Hanging Feeder – Best for Hanging Setups
Little Giant® Hanging Metal Poultry Feeder | Chicken Feeder | Outdoor Hanging Bird Feeder | Galvanized Steel Feed Container with Hanging Handle | 40 Pound
Capacity: 40 lb
Material: galvanized steel
Mount: hanging handle
Weight: 5 lb
Pros
- Heavy-gauge galvanized steel resists rust
- Small trough stops birds perching in feed
- Simple to assemble and refill
- Hanging handle saves coop floor space
Cons
- Ships with no lid
- Feed flow sometimes stops and needs a shake
- No rodent or wild-bird protection
- Top bars can loosen under a full load
This is the simplest feeder here and the easiest to hang. Forty pounds of feed in a five-pound galvanized body, suspended from the included handle, with a small trough that birds physically cannot sit in. That last point is why it wastes so little for a gravity feeder.
Raising it off the ground keeps feed out of the bedding, saves floor space in a crowded run, and stops the scratching that pulls feed out of an open pan. The tray bracket sets pan height, so you can dial the port position for the birds you actually have.
The limitation is the top of the unit, which is bare. It ships without a lid, so it belongs under a roofed run or under a cover you add yourself, and it has no sealed opening, which means no meaningful rodent or wild-bird protection. Buyers improvise with a cut bucket lid and report it works well enough.
Two more practical notes: feed occasionally stops flowing and needs the unit shaken or spun down to restart it, and the metal bars that hold the top and bottom together can loosen under the weight of a full feeder. Neither is a dealbreaker, but both are real.
Who this feeder suits
This fits a covered run or coop with a solid roof, a 20 to 30 bird flock, and anyone who wants one cheap metal feeder to start. It is also a good match for young growers, since the small trough keeps pullets from bathing in their own feed.
Who should skip it
Skip it on open pasture, in rodent country, or anywhere wild birds have access. If you already know you will be improvising a lid and still chasing rats, the money is better spent on a feeder that closes properly.
5. RentACoop 40 lb Treadle Feeder – Best for Rats and Small Birds
RentACoop Automatic Treadle Chicken Feeder, Rat Proof No Waste, 40 lb
Capacity: 40 lb
Material: galvanized metal, stainless hardware
Weight: 27.6 lb
Step: detachable weight
Pros
- Treadle and latched lid block rats
- mice and wild birds
- Adjustable feed-flow plate works for pellets or grains
- Detachable step weight lets bantams trigger it
- Anti-roost lid and blinders cut side spills
Cons
- Does not stop squirrels
- Some units arrive bent or scratched
- Lid latch can slip open in storms
- Treadle plate heats up in direct sun
This is the treadle to buy if your flock contains bantams or silkies alongside standard birds. The detachable step weight is the detail that makes it work, because you can lighten the trigger until the smallest bird in the flock can open the lid on its own.
Everything else is thorough. The grate in the trough stops billing, the adjustable feed-flow plate sits higher for pellets or lower for crumble and grains, the safety blinders force front-only feeding, and the optional step lock shuts the feeder completely overnight so nothing walks in after dark.
Roughly ten days of feed for about nine chickens is the manufacturer’s figure, and owners credit the build with real longevity, which is unsurprising at 27.6 lb of galvanized metal with stainless hardware. The anti-roost lid, perforated step and raised step for uneven ground show this one was designed for actual outdoor runs.
It is not perfect sealing. Squirrels are heavy and clever enough to learn the treadle, some units arrive with bent parts or loose rivets, and owners report the latch slipping so rain gets in during storms. Check the latch in a wind before you rely on it.
Who this feeder suits
This suits a 15 to 25 bird flock with mixed sizes, a family that wants to leave the step locked while the flock is on holiday, and anyone who switches between pellets and scratch grain. The step lock is the feature that changes weekend plans.
Who should skip it
Skip it if squirrels are the established problem, since this is the one weakness the reviews name repeatedly. Anyone with a mixed flock including ducks or geese should also choose a trough instead, because they will crowd and tip a treadle unit.
6. Tgeyd 95 lb Ten-Port Feeder – Best for Huge Flocks
95 lb Chicken Feeder with 10 No-Waste Ports – Extra-Large Galvanized Metal Poultry Feeder with Adjustable Height Heavy-Duty Stand – Outdoor Feed Box for Chickens, Ducks & Geese
Capacity: 95 lb
Material: galvanized steel
Ports: 10
Stand: height-adjustable
Pros
- 95 lb capacity means rare refills at scale
- Ten angled ports let a big flock eat at once
- Adjustable stand covers chicks through adults
- Riveted handles help when it is full
Cons
- Newer listing with a smaller review base
- Ten ports pull feed faster
- 19.8 lb empty weight is heavy to move alone
When a flock moves from 50 birds to 100, refill frequency becomes the whole problem, and this is one of the two biggest hoppers in the guide at 95 lb. Ten angled no-waste ports mean the flock is not queuing, which is the other half of the scale problem: bully hens cannot monopolise a feeder with ten mouths on it.
The adjustable stand is genuinely useful across a growing flock. Turn it up for pullers, level it for adult layers, and raise it further for ducks and geese, which need the height to reach comfortably. The hinged locking lid and riveted side handles make it manageable even when full.
At 23.6 by 12.2 by 25.8 inches it is a tall structure, and the ports are the highest in the guide, so watch that young birds cannot reach feed they should not be eating yet. Galvanized steel handles the weather side easily; the open question is the rivets and welds over a long winter.
Be aware of the review history. With 169 reviews, this is a newer listing, and there is less long-term data on it than on the established brands, which is worth weighing if you are buying for a flock you plan to keep for years.
Who this feeder suits
This is built for flocks of 60 to 150 birds, or 30 to 50 large birds eating big rations. It also suits a mixed flock of chickens, ducks and geese, since the height adjustment and the ten ports suit birds that feed differently.
Who should skip it
Skip it for a flock under 30 birds, where you will be lifting far more feed than you need. Anyone with limited strength should also weigh the 19.8 lb empty body against a smaller unit you can carry one-handed.
7. GADFISH 55 lb Eight-Port Feeder – Best for Rain and Muddy Runs
GADFISH 55 lbs Large Capacity Automatic Chicken Feeder – 8 Feeding Ports, No Waste Chicken Feeder, Height-Adjustable Legs & Secure Locking Lid for Chickens, Ducks & Poultry
Capacity: 55 lb
Material: coated galvanized sheet
Ports: 8
Lid: conical metal
Pros
- Conical lid sheds rain and stops perching
- Tool-free leg rotation adjusts height
- Wider base contact resists sinking in mud
- Coated metal resists rust and chewing
Cons
- Fixed lid is not rodent proof
- Rotating legs are less precise than bolt adjustment
- Shorter review history than older brands
The conical lid is the reason to buy this one. Flat-lid feeders become perches, and perches become a fouled feeder, whereas a cone sheds rainwater after rain and gives birds nothing to stand on. On a wet run that is a meaningful difference over a season.
The eight ports and 55 lb capacity sit in the useful middle of the range. It is big enough for a 25 to 40 bird flock without a forklift, and the aluminum-coated galvanized sheet wipes clean easily and resists the chewing that ends plastic feeders.
Height adjustment is a leg rotation rather than a bolt in a slot, which means no tools and fast changes as birds grow, at the cost of precision. The wider base footprint also spreads weight, which helps on soft grass and mud where a narrow stand tips and sinks.
One thing to be clear about: the lid is fixed, not latched, so this is not a rodent-proof feeder. It keeps rain and large birds out, and it will slow a determined rat very little. Expect to add a metal storage bin for your feed sack.
Who this feeder suits
This suits a 25 to 40 bird flock in a wet climate or on soft ground, and anyone raising birds from pullets to adults on the same unit. It works well as the second feeder alongside a treadle, since the cone drains and cleans quickly.
Who should skip it
Skip it where rodents are already inside the coop, and skip it if you need precise port height for chicks, since rotating legs are coarse. Buyers who want a long service record should weigh the shorter review history against older models.
8. BUYYAH 100 lb Feeder – Best for Maximum Capacity
BUYYAH 100lb Capacity Automatic Chicken Feeder
Capacity: 100 lb stated
Material: galvanized steel
Weight: 27.6 lb
Lid: hinged, waterproof
Pros
- Largest stated capacity in the guide
- Galvanized body resists extreme weather
- Hinged waterproof lid keeps feed dry
- Port hole covers block openings you do not need
Cons
- Predrilled holes often do not line up
- Sharp burrs and a bulging side panel
- Loose lid hinge lets water in
- Owners report real feed waste
This is the biggest hopper listed, and the manufacturer claim is that 100 lb covers roughly 18 hens for 28 days. Whether or not your birds match that figure, the point is that you can buy feed in bulk and refill rarely, which is the whole argument at 100 birds and up.
Two thoughtful touches: the waterproof hinged lid keeps feed dry without lifting a solid panel, and the included hole covers let you block unused ports, which reduces spillage while you are still ramping up the flock. The galvanized body is rated for extreme weather.
Reviews are sharply split, and it is worth reading the complaints. Owners mention predrilled holes that do not line up, sharp burrs from cut screws, a side panel that bulges when tightened, and a lid hinge held by two screws and nuts that loosens and lets water in. That is a lot of small irritation for a feeder you will move rarely.
Feed waste is also reported despite the no-waste design, and the stated dimensions are much smaller than a 100 lb hopper would suggest, so check the space in your run before committing. Plan on spending an afternoon with files and a screwdriver after delivery.
Who this feeder suits
This suits a 100 to 200 bird flock, or anyone who wants to buy feed by the sack and store it in the feeder rather than in a second container. It is also reasonable for households that keep an eye on assembly.
Who should skip it
Skip it for smaller flocks, where you will refill twice a year and spend your effort on assembly instead. It is also a poor fit for anyone who needs the feed to stay dry in storms without checking the lid hinge every week.
9. Dogetgd 85 lb Multi-Port Feeder – Best for Mixed Species Flocks
Automatic Chicken Feeder No Waste Metal Poultry Feeder Large Capacity 85lbs for Chickens, Geese, Ducks, Turkeys, Quails (10-Port)
Capacity: 85 lb
Material: rust-resistant metal
Ports: 4, 6 or 10
Weight: 23.05 lb
Pros
- 85 lb lasts about a month with 12 chickens
- Owners report feed staying dry in heavy rain
- Stable base does not tip when birds climb on
- Assembles in five minutes to half an hour
Cons
- Not rodent or squirrel proof
- Some units rust and take in water over time
- Chickens can pull the port hoods off
- Small birds struggle to reach the ports
Listing chickens, geese, ducks, turkeys and quails on one feeder is a claim worth checking, and on the port side it holds up. Port configurations come in 4, 6 and 10 openings, so you can match the feeder to the flock rather than fitting the flock to the feeder.
Owners with experience running mixed birds report the weather performance as the standout: feed staying bone dry through storms, and a stable base that does not tip even with birds on top. The wide top opening makes fast refilling easy and the smooth metal surfaces wipe clean.
At 85 lb the refill math is what makes it interesting at scale. The stated figure is that a single fill lasts roughly a month with 12 chickens, and several owners report consolidating two smaller feeders into one unit to cut trips to the feed store.
The honest negatives: it is not rodent or squirrel proof, squirrels open it and accelerate feed loss, some units develop rust and water intrusion that clumps the feed, and chickens can dismantle the coloured port hoods over time. Watch it in a wet climate.
Who this feeder suits
This suits a mixed flock of chickens with ducks, geese or turkeys in a 40 to 80 bird range, especially where the run gets rained on from the side. Buyers who consolidated multiple small feeders report the biggest drop in daily chores.
Who should skip it
Skip it on rodent-heavy ground and in mixed-age flocks with chicks, since the ports are out of reach for the smallest birds. If you are in a high-rainfall area, check the seams at the start of each season for early rust.
10. TGEYD 50 lb Eight-Port Feeder – Best Budget Pick
TGEYD 50LB Large Automatic Chicken Feeder – 8 Feeding Ports, No-Waste Poultry Feeder, with Adjustable Legs & Locking Lid
Capacity: 50 lb
Material: galvanized steel
Ports: 8 openings
Included: 2 feeders
Pros
- Lowest cost per pound of capacity in this group
- Metal resists chewing that destroys plastic
- Locking lid has kept skunks and opossums out
- Adjustable legs lift feed off the ground
Cons
- No-waste claim unmet for some flocks
- Leg height needs adjusting as birds grow
- Unsealed screw holes let rain in
- Real capacity below the stated 50 lb
Two of these ship in the box, which makes this the easiest way to cover a large flock without a second purchase. Fifty pounds per unit, eight feeding openings so the flock eats together, and adjustable legs that keep the feed off damp ground.
The locking lid is the sleeper feature at this level. Owners report it keeping opossums and skunks out of the feed, and because it locks, you can close the feeder overnight rather than relying on birds as the only thing between a rodent and a full hopper.
Metal is the other argument. Birds that chewed through plastic feeders leave this one alone, and the galvanized body is built for permanent outdoor placement. For a 40 to 60 bird flock, two units give you enough capacity and enough ports to break dominance.
The complaints are consistent. The no-waste claim does not hold for every flock, owners report feed on the ground, the legs need resetting as birds grow, real capacity lands below the stated 50 lb depending on pellet size, and unsealed screw holes let water in during heavy rain.
Who this feeder suits
This suits a 40 to 60 bird flock on a budget, and anyone who wants metal rather than plastic without paying for a treadle. The two-unit pack is the reason it makes sense at this flock size rather than a single small unit.
Who should skip it
Skip it in exposed, high-rain runs where the screw holes will fill with water, and skip it if feed waste is your top concern. Anyone counting on a rodent-proof seal should know a locking lid is a delay, not a barrier like a treadle.
How Many Feeders Your Flock Actually Needs
For planning, we use roughly 0.5 lb of feed per bird per day, which is a sensible planning figure for a layer flock on a mixed indoor and outdoor routine. Check it against your own birds’ consumption after one week, because free-ranging layers eat noticeably less than confined ones. Multiply your bird count by 0.5, and you know how many pounds a day your flock needs.
Then work from feeder capacity, and add one more feeder than the math suggests. A flock that shares two feeders eats calmer and wastes less than a flock crammed around one, because there is no queue and no bully hen holding the only port.
20 birds: one 40 to 50 lb feeder covers the flock, but two is better. Twenty birds at 0.5 lb a day use about 10 lb daily, so a 50 lb fill lasts close to five days. Two feeders also gives you a spare if one floods.
30 birds: two feeders minimum, 50 lb class. Daily use is around 15 lb, so each unit is empty in a little over three days, and you are refilling every second day.
50 birds: two 50 to 55 lb units, or one 85 to 95 lb feeder with several ports. Daily use hits 25 lb, which is where a 40 lb feeder becomes a daily chore and waste starts climbing.
100 birds: two feeders of 85 to 100 lb each, or three 50 lb units. Daily use reaches 50 lb, so anything under 60 lb of total capacity means refilling every day in warm weather.
200 birds: four to five feeders in the 85 to 100 lb class. At 100 lb of daily demand, no single portable feeder is a sensible answer, which is where fixed silo storage and a motorized line feeder start to make more sense.
Port count follows a similar rule. Eight to ten ports keeps a flock of 40 or more from queueing, and two or three ports suits flocks under 15. Anything above that and you are adding ports to solve a dominance problem that two separate feeders solve more cheaply.
What to Look for in a Large-Flock Feeder
Capacity first, everything else second. The single biggest predictor of wasted feed and wasted time is a hopper that is too small for the flock. A 30 lb feeder for 40 birds empties before the flock has finished eating, birds rush the ports, and scratched-out feed lands on the ground. Buy for the flock you will have in a year, not the flock you have now.
Know which feeder type you are buying. Four types cover almost every large-flock situation, and each fails differently:
Gravity or hanging feeders keep feed off the ground and pour it on demand, with no moving parts to fail. They are the cheapest and the easiest to service, and they offer almost no pest protection.
Treadle feeders open only while a bird stands on the step, which is why they are the only genuinely rodent-proof option in this guide. The cost is a training period and a minimum bird weight.
Silo and port feeders hold bulk feed in a hopper and let birds reach it through angled ports, which cuts spillage and gives you a large capacity in a small footprint. The ports become a squabble point if you have fewer than six.
Trough feeders are open rails that many birds eat from at once. They waste more feed than any other type, and they are the right answer for ducks, geese and mixed flocks that cannot work a treadle.
Treat rodent-proofing as a system, not a product. A feeder with a closed lid is only half of it, because the open feed sack beside it is an open buffet. Store feed in a metal container with a tight, rodent-resistant lid, inside a metal or hard-sided bin, and only carry out what you will use in a week. On r/BackYardChickens the pattern is consistent: even high hanging feeders get raided, and the keepers who solved it paired a treadle with metal storage. If wild birds are the problem, the same logic applies, and the feeder designs built to deter them are covered in our wild bird feeder guide and our squirrel proof feeder picks.
Galvanized metal beats plastic outdoors. Owners of plastic dome feeders commonly report yellowing and cracking after one or two seasons, and once a hopper cracks it leaks feed and takes on water. Galvanized steel, whether as heavy-gauge body or coated sheet, holds up far longer. Plastic still makes sense for weight and cost, provided you accept replacing it and storing feed dry elsewhere.
Check the weather sealing, not just the lid. A hinged lid is only as good as its seal and its screws. Buyers report lids that slipped unlatched and let rain in, and screw holes that were never sealed. Look for a recessed channel or port overhang that sheds water, a rain hood that seats firmly, and a cone or slope that drains rather than pools.
Count ports against flock size, and check rooster access. Roosters and large breeds need a large port or a trough; small bantams cannot use a large port at all. Treadle feeders with a detachable step weight solve this for mixed-size flocks, and are the reason to prefer them over a fixed-trigger model. Eight to ten ports is the practical minimum once a flock passes 40 birds.
Refilling and cleaning decide whether you keep using it. A wide-mouth opening that lets you refill at ground level, or a grate that unclips for cleaning, will be used far more often than a hopper you have to unbolt. This is also where a 50 lb plastic unit can genuinely beat a metal one: you can tip it forward and scoop feed in rather than lifting the whole thing.
One more point on timing. If you plan to be away, the feeder choice matters more than the waterer choice. A port feeder with a locking lid that you close on departure, plus a large capacity, is what lets a 50 bird flock get through a long weekend without daily attention. If you already have a set of feeders and are weighing an upgrade, our smaller flock feeder roundup is the quicker read.
Frequently Asked Questions
What is the best large chicken feeder for a flock of chickens?
For most flocks of 20 birds and more, the OverEZ 50 lb gravity feeder is the best all-round large chicken feeder. It holds 50 lb, keeps rain out with a recessed port channel, and refills at ground level. Where rats are the problem, choose a treadle feeder such as the Grandpa’s 40 lb, which only opens while a bird is on the step.
How many feeders should you have for 20 chickens?
Two feeders for 20 chickens. At roughly 0.5 lb of feed per bird per day, a flock of 20 uses about 10 lb a day, so one 50 lb feeder covers about five days but leaves a single point of failure. Two 40 to 50 lb feeders also break dominance, so bully hens cannot claim the only feeding ports.
Are treadle feeders better than gravity feeders?
Treadle feeders are better for rodent control and feed waste, because the lid opens only while a bird stands on the step. Gravity feeders are cheaper, lighter, need no training and suit young or mixed flocks. Choose a treadle for adult standard birds where rats are present, and a gravity or port feeder for pullets, bantams and mixed-species flocks.
What is the 90/10 rule for feeding chickens?
The 90/10 rule means roughly 90 percent of a chicken’s diet should come from a complete layer ration and about 10 percent from treats, scratch grains and forage. In practice, treat scraps and kitchen leftovers should stay near that tenth. At large-flock scale, treat feeding also pulls birds off the feeder and increases waste, so feed the ration in the feeder and forage separately.
What color calms chickens?
Calmer poultry is generally the pale end of the range rather than the bold end. Many keepers report that darker birds appear more nervous and skittish, while light birds seem steadier, so a calm flock reads lighter. Colour does not change temperament on its own, and handling, noise, lighting and flock stability matter more.
Final Verdict
For most large flocks, the OverEZ 50 lb gravity feeder is the pick: 50 lb of capacity, rain-shedding ports, a wide mouth you can refill at ground level, and a body light enough to move. It is the one we would put in the run of a 20 to 30 bird flock tomorrow.
Beyond that, the decision is about your worst problem. Rats mean the Grandpa’s 40 lb treadle or the RentACoop 40 lb treadle with its optional step lock. Ducks and geese in the flock mean the RentACoop 50 lb galvanized trough. Flocks of 60 birds and up mean the 95 lb or 100 lb hoppers, with two units rather than one.
Whichever you choose, size it with the math above rather than the bird count on the label, and pair the feeder with metal feed storage. That combination is what makes the best poultry feeders for large flocks actually save feed instead of feeding the local rodent population alongside your hens.
