Why do chickens flap their wings

By John Walker · Backyard chicken keeper in Dallas, Texas since 2017

Why do chickens flap their wings? Chickens flap their wings for many reasons, and most of them are normal, healthy behaviour. A chicken may flap to stretch after sitting, to cool down on a hot day, to shake off dust after a dust bath, to show off to a hen, or to warn the flock of danger. The flap looks the same at a glance, but the context tells you what it means: a bird that flaps and stretches in the morning is waking up, while a bird that flaps and runs for cover is sounding an alarm. This guide explains the seven main reasons chickens flap their wings, and when a flap is a sign of a problem.

Why do chickens flap their wings? The main reasons

Why do chickens flap their wings? The most common reason is stretching. A chicken that has been sitting for a while will stand up, stretch one leg and one wing out to the side, and then flap both wings a few times.

That stretch is like a person stretching after sitting at a desk, and it is a sign that the bird is comfortable and healthy. You will see it often in the morning, when the birds come out of the coop, and after a dust bath.

Other common reasons include cooling down, shaking off dust, mating, showing dominance, and sounding an alarm. A flap can also be a sign of a problem, such as a bird that is too hot, a bird with mites, or a bird that is trying to fly. The context is what tells you which reason it is, and this guide works through each one in turn.

Stretching and waking up

Stretching is the most common reason for wing flapping, and it is a good sign. A chicken will stand, stretch one wing and the leg on the same side outwards, hold the stretch for a second, and then flap both wings.

That stretch wakes up the muscles after sitting, and it is a sign that the bird is relaxed and healthy. You will see it when the birds come out of the coop in the morning, after they have been sitting on the nest, and after a dust bath.

A bird that stretches often is a bird that is comfortable in its surroundings. If your birds never stretch, it may be because they do not have enough space, because a bird needs room to stretch its wings. Make sure the coop and run give the birds enough space to stretch, flap, and move freely, because a bird that cannot stretch is a bird that is stressed.

Reason	What it looks like	Normal?
Stretching	Slow flap after sitting	Yes, healthy
Cooling down	Wings held out, gentle flap, panting	Yes, help with shade and water
Dust bathing	Hard flap after a dust bath	Yes, healthy
Mating display	Rooster circles hen, flaps	Yes, normal
Alarm	Sudden hard flap, running	Yes, check for danger
Mites or injury	Constant flapping, drooping wing	No, check the bird

Cooling down on a hot day

Chickens flap their wings to cool down, because they cannot sweat. On a hot day, a chicken will hold its wings out from its body and flap them gently, which moves air over the skin and helps heat escape. You will also see the bird panting, which is breathing with its beak open.

And holding its wings away from its body even when it is not flapping.

If your birds are flapping to cool down, help them. Give them shade, cool water, and a shallow tray of water to stand in, and make sure the coop has good ventilation. Do not hose a chicken down, because wet feathers can chill a bird once the sun goes down. If a bird is panting heavily, holding its wings out, and looking dull, it may have heatstroke, and it needs shade and cool water at once.

Dust bathing and shaking off

A dust bath is a chicken's way of cleaning itself, and it ends with a good wing flap. The bird digs a shallow hollow in dry soil or sand, lies in it, and kicks dust through its feathers. The dust absorbs oil and helps to control mites, which are tiny parasites that live on the skin.

After the bath, the bird stands up, shakes itself, and flaps its wings hard to shake the dust out of its feathers.

That flap is a sign of a healthy bird that is looking after itself. Make sure your birds have a dry, dusty place to bathe, because a bird that cannot dust bathe is more likely to get mites. A dust bath can be a patch of dry soil in the run, or a shallow tray filled with sand, wood ash, and a little diatomaceous earth, kept under cover so it stays dry.

Mating, showing off, and dominance

Roosters flap their wings to show off to hens and to show dominance to other roosters. A rooster that is courting a hen will drop one wing, circle her, and flap his wings, which is part of the mating dance.

A rooster that is challenging another rooster will stand tall, fluff his feathers, and flap his wings hard, which is a display of size and strength.

Hens also flap to show dominance, although they do it less often than roosters. A hen that is high in the pecking order may flap at a lower-ranking hen to make her move, and a hen that is defending a nest box may flap at another hen that comes too close. That flapping is normal flock behaviour, and it is only a problem if it turns into constant bullying or feather pecking.

Alarm and escape

A sudden, hard flap is often an alarm. If a chicken sees a hawk, a dog, or another danger, it will flap its wings, squawk, and run for cover, and the rest of the flock will follow. That flap is part of the alarm call, and it is a sign that the bird has seen something it fears.

You will also see it when a bird is startled by a sudden noise or movement.

If your birds flap and run often, look for what is scaring them. A hawk overhead, a dog at the fence, or a loud noise can all cause it. Make sure the run has cover, such as a roof or a bush, so the birds can hide when they are scared. A bird that is always nervous and always flapping may be stressed, and it needs a safer, calmer run.

When wing flapping is a sign of a problem

Most wing flapping is normal, but there are a few cases where it is a sign of a problem. A bird that flaps a lot, scratches, and has bare patches may have mites or lice, which are parasites that make the skin itch.

A bird that flaps one wing and holds it drooping may have a broken wing or a dislocated joint, and it needs a vet. A bird that flaps and pants on a hot day may have heatstroke.

A young bird that flaps and tries to fly over the fence is not ill, but it needs a taller fence or a covered run. A bird that flaps and cannot fly, even though it tries, may have clipped wings or an injury. Watch the context: a bird that flaps after a dust bath is healthy, while a bird that flaps and scratches all day needs checking for parasites.

Wing flapping is mostly normal, healthy behaviour, and it is a sign of a bird that is comfortable, active, and looking after itself. A flap after sitting is a stretch, a flap after a dust bath shakes the dust out, and a flap on a hot day helps the bird cool down. Learn to read the context: a bird that flaps and stretches in the morning is waking up, while a bird that flaps constantly, scratches, or holds a wing drooping needs checking for mites or an injury. Watch your birds, give them space to stretch, and most flaps will be a good sign.
