Why Won't My Chickens Go in the Coop at Night?
Chickens refuse the coop at night because they have not learned it is home, prefer to roost high, or are driven out by mites. Learn how to train them and keep them safe.
Dusk is falling, the rest of the flock has tucked itself in, and a few stubborn birds are still milling around the run or, worse, fluttering up into a tree. Chasing chickens around in the dark is nobody's idea of a relaxing evening, and it is also a genuine safety problem, because a bird that will not go in is a bird exposed to predators. The good news is that this is almost always a training issue with a reliable fix.
Chickens refuse to go into the coop at night most often because they have not yet learned it is home, especially when newly moved. Other common reasons are a natural urge to roost as high as possible, mites making the coop miserable, and roosts set lower than the nesting boxes. The core fix is to confine the flock to the coop for several days so they bond to it, then reinforce the routine at dusk.

Common causes, most likely first
They have not learned the coop is home
This is the number one reason, especially with a new flock, recently moved birds, or new additions. Chickens return at night to the place they have imprinted on as their safe roosting spot, and a coop they have not bonded to does not yet register as home. The remedy is simple but requires patience: keep them confined to the coop, or the coop and attached run, for several days to a week so they learn it is where they live and sleep. Once they have that association, they will put themselves to bed there at dusk.
The instinct to roost high
Chickens are driven to sleep on the highest perch available, a survival instinct inherited from wild ancestors that roosted in trees away from ground predators. If a tree branch, fence rail, or shed roof is higher and more appealing than the coop roosts, some birds will choose it. Make the coop the best high option by setting roosting bars above the height of the nesting boxes, and remove or block tempting outdoor perches.
Mites in the coop
If your flock suddenly abandons a coop they once used happily, suspect red mites. These parasites hide in cracks and crevices by day and swarm onto roosting birds to feed at night, turning the coop into a torment. Birds may refuse to enter and roost outside to escape. Inspect the roosts and crevices after dark with a flashlight, and if you find mites, treat the coop thoroughly and repeat.
Poor roost setup
Sometimes birds go into the coop but pile into the nesting boxes instead of the roosts, because the boxes are higher. Keep roosting bars clearly above the boxes, make them wide enough at around two to four inches, and ensure the coop is not overcrowded or drafty.
What to do
- Confine the flock to the coop, or coop and run, for several days to a week so they learn it is home.
- At dusk, herd stragglers in gently and lure them with a treat like scratch grains scattered inside.
- Be consistent, repeating the routine at the same time each evening until the habit sticks.
- Set roosting bars higher than the nesting boxes, and remove tempting outdoor perches and low tree branches.
- Check the coop at night for red mites and treat thoroughly if you find them.
- Use a dim evening light inside to draw birds in as the sky darkens.
- Once the flock reliably puts itself to bed, an automatic door can close behind them to keep predators out.
| Situation | Likely cause and fix |
|---|---|
| New or recently moved birds | Not home yet, confine to train |
| Roosting in trees or on fences | Instinct to go high, raise roosts, remove perches |
| Suddenly avoiding a familiar coop | Red mites, treat the coop |
| Sleeping in nesting boxes | Roosts too low, raise them above boxes |

When to worry
Most coop-refusal problems are behavioral and solved with training, patience, and a few coop tweaks. There is no medical emergency in a flock that simply needs to learn its way to bed. The real urgency is safety: every night a bird sleeps outside the coop, it is exposed to raccoons, owls, foxes, and weasels that hunt after dark, so resolving the issue promptly genuinely protects lives.
Look beyond training, and consider a poultry or avian vet or your local extension office, if a bird that used to go in now stays out because she cannot, rather than will not. A chicken who is reluctant to roost because she is being badly bullied, is too weak or sick to fly up, is injured, or is suffering a heavy mite infestation needs help with the underlying problem. Watch the flock dynamics and check the bird over. For the typical case of birds that just have not learned where home is, a week of confinement and a consistent dusk routine will have them tucking themselves in like clockwork.
Frequently Asked Questions
Why won't my new chickens go into the coop at night?
Newly moved birds simply have not learned that the coop is home yet. Chickens return to roost in the place they have imprinted on as safe, so a new flock or new arrivals need time and training to recognize the coop. The standard fix is to confine them inside the coop and run for several days to a week so they bond to it, then let them out, after which they should head back in on their own at dusk.
How do I train chickens to go into the coop at night?
Keep them shut in the coop for a few days to a week so they learn it is home, then allow free time. At dusk, gently herd stragglers in, and use a treat like scratch grains scattered inside to lure them. Doing this consistently at the same time each evening builds the habit. A dim light inside as the sky darkens can also draw them in. Within a week or two, most flocks roost reliably on their own.
Could mites be keeping my chickens out of the coop?
Yes, this is a commonly overlooked cause. Red mites hide in coop cracks during the day and crawl onto roosting birds to feed at night, making the coop a miserable place to sleep. Chickens may refuse to go in and instead roost outside to escape the biting. If your birds suddenly avoid a coop they used happily, inspect the roosts and crevices at night with a flashlight for mites and treat the coop thoroughly.
Why do my chickens roost in trees instead of the coop?
Roosting up high is a deep natural instinct, since wild ancestors slept in trees to stay safe from ground predators. If birds find a tree, fence, or rafter higher and more appealing than the coop roosts, they may choose it. Make the coop the most attractive high spot by providing roosts higher than the nesting boxes, removing tempting outdoor perches, and confining the flock to retrain them. Tree roosting leaves birds dangerously exposed to predators.
Can an automatic coop door help?
An automatic door is a great convenience, but it does not teach birds to go in. The flock must already be trained to put themselves to bed in the coop, and then the door simply closes behind them at dusk and opens at dawn, protecting them from night predators without you having to be there. If birds are not yet roosting inside reliably, train them first, then add the door to automate the routine.
Why won't my chickens use the roost inside the coop?
Birds prefer to sleep on the highest available spot, so if your nesting boxes sit higher than the roosts, they will pile into the boxes instead, which causes messy, soiled eggs. Make sure roosting bars are clearly higher than the nesting boxes. Also check that roosts are wide enough, around two to four inches, and comfortable. Some flocks also avoid roosts due to mites, drafts, or overcrowding, so address those too.
Is it dangerous for chickens to sleep outside?
Yes, very. Chickens that roost outside the coop are extremely vulnerable to night predators such as raccoons, owls, foxes, and weasels, which do most of their hunting after dark. A bird asleep on the ground, a fence, or a low branch is an easy target. Getting your flock to reliably shelter in a secure, predator-proof coop each night is one of the most important things you can do for their safety.
