A roost is the most boring thing in a coop. It’s also the one piece your flock uses every single night, so it’s worth getting right.
Below are six roost setups that work. Most of them are cheap or free. But every one of them only works if it hits a few numbers. How much bar does each bird get? How high does it sit? Spacing matters too, from the next bar and from the wall.
I didn’t want to guess at those numbers, and I didn’t trust forum posts for them either. So I went through the university extension guides instead, five of them, and I name the source every time a number shows up. Numbers first, then the builds.
The Numbers Every Roost Has to Hit
Here’s what the extension guides say, side by side. Where two of them disagree, you get both.
- Bar per standard bird: 5 to 12 inches (Oregon State says 5 to 10, Penn State 6, Kentucky about 12)
- Bar per bantam: 4 inches (Penn State)
- Height for standard hens: 18 to 24 inches (Penn State; Oregon State says 2 feet)
- Height for bantams: 12 to 18 inches (Penn State)
- Space between bars: 10 inches to 1 foot (Oregon State, Penn State)
- Bar to wall: at least 1 foot (Kentucky)
- Highest perch in the coop: no more than 4 feet (Penn State)
- Bar size: 1 to 2 inches square, top edges rounded (Oregon State)
The bar length is the one I’d pay attention to. Oregon State’s 5 inches a bird and Penn State’s 6 are the tight end. Kentucky’s guide asks for about a foot of usable roost per bird, and says the extra room cuts down on birds pooping on each other. A few more inches of lumber costs next to nothing, so I’d build for the bigger number.
Height is where the guides spread out, and that surprised me. Kentucky allows anything from 16 to 40 inches. Dr. Jacquie Jacob’s perch article for the extension network goes higher, about 3 feet for the lowest bar, so the birds on the floor can’t peck at the one sitting on it. Penn State sets the ceiling at 4 feet. Go higher than that, it says, and birds can hurt their legs and wings getting up and jumping down.
One more thing from Jacob’s article: get perches in front of your birds while they’re young. Research has shown, she writes, that chicks raised without perches have a harder time using them as adults.
Want those inches added up? Our Chicken Coop, Run & Roost Size Calculator does it:
- Replace the 6 in Standard hens with your standard-size birds, roosters too.
- Enter any bantams in Bantams.
- Find the two roosting bar lines under Inside the coop.
They’re Penn State’s count and Oregon State’s range. Kentucky’s foot or so of usable bar, which I’d build for, isn’t shown. Big birds are different: the tool gives Large breeds standard bar, Kentucky wants more, and Penn State says large structured or meaty breeds shouldn’t perch. Read Idea 6 before you enter any.
Idea 1: A Plain Square Bar You Can Lift Out
This is the one I’d build first. Oregon State’s coop guide says wood gives the best footing, and it asks for 1- to 2-inch square lumber with the top edges rounded off. Too small or too round and you can get foot problems. Jacob’s article adds that more laying hens use a square perch than a round one.
A 2×4 on edge is 1.5 inches across the top, which lands right inside Oregon State’s range. Plenty of keepers turn theirs wide side up in winter so the hens can sit down over their toes. Honestly, that’s barn wisdom, not research. I looked and couldn’t find a study on it either way.
Round over the top edges with sandpaper or a block plane. Then set the bar in notches or open brackets so it lifts straight out. Jacob’s article says roosts should come out so you can clean the manure under them, and Kentucky’s guide says once a month is typical for that job.
Oregon State also lists pressure-treated and latex-painted wood as easy to clean. I’d still use plain lumber for a bar hens sit on all night, but that’s my call, not theirs.
Idea 2: A Ladder Roost, Built Shallow
A ladder roost is a set of bars stepped up and back, like a ladder leaned on the wall. Oregon State shows two layouts in its guide: a bed, where the bars sit level side by side, and a ladder, where each bar is higher than the last. Both work.
The thing about a ladder is the pecking order. Jacob’s article says the dominant hens take the higher perches at night. So the top rung fills first, and the hens lower in the order get what’s left. Make each bar long enough and they still get a spot.
Keep the steps shallow. A big drop between bars makes birds misjudge their landings and hit the bars, Jacob writes, which hurts the keel (the breastbone). Leave clear floor in front of the ladder too, so a bird jumping down has room to land.
Space the bars 10 inches to a foot apart and keep the top one under 4 feet. If I were building one this weekend, I’d measure the drop between bars before anything else. That’s pretty much it.
Idea 3: A Tree Branch From Your Own Yard
A straight, dry branch makes a free roost. Pick one on the thick side. Oregon State’s warning about bars that are too small or too round applies to branches too, so go thicker rather than thinner.
The catch is mites. Bark is full of cracks, and the chicken mite loves cracks. The University of Florida’s entomology page on it says it’s also called the poultry red mite or the roost mite. It hides in cracks and nest litter by day, then feeds on birds at night.
Jacob’s article says wooden perches are very sensitive to red mites. So I’d peel the bark off and let the branch dry out well. Then I’d set it in brackets like the square bar, so you can pull it and look at it. If mites ever turn up in it, a branch is cheap to toss and replace.
Idea 4: A Pallet, After You Read the Stamp
If a feed store or a neighbor will give you a pallet, the slats come apart into decent roost bars. Before you take one home, look for the stamp on its side.
Pallets made for shipping across borders carry a mark (the ISPM 15 stamp), and USDA APHIS lists the two treatment codes you’ll see on it. HT means heat treated. MB means methyl bromide, a fumigant. I’d only use an HT pallet for a roost, and I’d pass on one with no stamp at all, since you don’t know what it’s been through.
Then check every slat for nails and splinters. Penn State’s housing guide says to get loose wire and nails out of the coop, along with anything else that has a sharp edge. Jacob’s article says perches shouldn’t have sharp edges either. Pallet slats are often thinner than a 2×4, too, so make sure one doesn’t bend once a full row of hens is sitting on it.
Idea 5: An Old Wooden Ladder, If the Paint Checks Out
An old wooden ladder leaned on the wall is the classic free roost. It works if the rungs fit the numbers above, so measure how far apart they are before you bring it in.
Lean it at a gentle angle. Kentucky’s guide wants a perch at least a foot from the next one, and a steep ladder puts each rung right under the one above it.
The real thing to check is the paint. US rules ban consumer paint that contains lead, and furniture painted with it, for anything made after February 27, 1978 (it’s in the federal rules at 16 CFR 1303). A painted ladder or an old crib from before then could carry lead paint. If you don’t know how old the paint is, I’d skip it. An unpainted ladder, or one you know is newer, is the safe pick.
Idea 6: A Low Roost for Small Birds, None for Big Meat Breeds
Not every bird should go up 2 feet.
Bantams get 4 inches of bar each, 12 to 18 inches off the floor, per Penn State.
Silkies, Oregon State says, should roost only 1 foot off the ground.
Big meat breeds are the odd ones out. Penn State’s guide says perches shouldn’t be used with large structured or meaty breeds at all, to prevent leg joint damage when they jump down. For those birds, skip the roost and keep their bedding clean and dry.
Running a mixed flock? Put a low bar in next to the main one. A square bar on two cinder blocks does the job, and you can lift it out like the others.
Where the Roost Goes in the Coop
A good bar in the wrong spot causes its own problems. Here’s the placement list, each line from the guide named:
- Not above the feeder or the waterer (Kentucky). Whatever’s under the roost gets pooped on.
- At least a foot out from the wall (Kentucky). Birds like to sit with their backs to the wall, so give them room to.
- Not right under a vent or window (Penn State, which says vents shouldn’t open directly over the perching area, to prevent drafts).
- Nest boxes at least 4 feet away from the roosts and 2 feet off the ground (Penn State).
- Out of your way at feeding time and when you gather eggs (Jacob).
Then take away the spots you don’t want them sleeping on. Penn State says to remove perching areas like window sills and nest box tops, even electric cords. Oregon State says a nest box roof sloped at 45 degrees keeps birds from roosting on top of the boxes.

Winter: Keep the Roost Dry, Not Warm
People ask about heating the roost every winter, and I get why. Nobody likes the thought of a hen out there at 10 degrees. Kentucky’s guide says birds tolerate low temperatures, but only if they’re dry, and that roosting keeps their feet off the floor and dry so frostbite doesn’t set in. Penn State says the same thing: poultry handle cold very well if they’re dry.
Jacob’s frostbite article says it’s more likely at night in a cold coop with poor ventilation and damp bedding. It hits combs and wattles, and sometimes toes. Roosters get it most, since their combs are bigger, but any hen with a large comb can get it too, like a Leghorn. Pea and strawberry combs get it much less.
She also says heat lamps are a fire hazard, and coops are lost to them every year. She calls coop management the real key. Flocks can do fine below zero, she writes, with a deep litter system and an in-bucket water warmer, and no outside heat at all. And if you see condensation on the windows in the morning, the coop needs more ventilation, not less.
Illinois Extension says to keep 6 to 12 inches of dry bedding, and that you shouldn’t see air moving the birds’ feathers in the coop in winter. So put the vent up high, at the roof or the eaves, and away from the roost.

Check the Roost at Night for Mites
Roost mites are the reason I’d make every bar removable, branch or not. Florida’s page says they feed at night and spend the day hidden in cracks and nests, so a daytime look can miss them. It suggests checking the birds at night.
It also says these mites can live up to 8 months without feeding, and that taking the birds out of the coop doesn’t get rid of them. So an empty coop can stay infested for most of a year.
So now and then, go out after dark with a flashlight. Lift a bar and look at its ends and at the brackets it sits in, since that’s the kind of crack they hide in. And don’t count on plastic to dodge them. Jacob’s article says red mites hide where plastic perches join together, too.
