How To Cool Chickens Down (And What NOT To Do!)

By Chicken Fans Editorial Team

Hot, tropical summer months can be unpleasant for many animals, including birds and chickens. As a chicken keeper, you’ll have to protect your flock from scorching heat and provide plenty of shelter and fresh cool water to help them stabilize their body temperature. But that’s not all you can do!

We’ll take you through the MUST DO’s, the CAN DO’s, and the DON’T DO’S. But we also address the signs of heat stress in chickens and determine how well they stand high temperatures.

Let’s get started!

Can chickens stand high temperatures?

Chickens take temperature changes reasonably well, but they stand cold temperatures better than hot ones. A chicken’s body fat, found under the skin, and their warm feathery coat protect them from low temperatures, but it makes them not fond of hot temperatures.

The most pleasant temperature for chickens is around 75 degrees Fahrenheit (24°C) or below. This depends on the chicken breed (chicken breeds with larger combs are more heath tolerant), but it’s best to take precautions when a heatwave is on its way.

Ambient temperatures of 85 degrees Fahrenheit (30°C) and more impact chickens negatively, causing a reduction in feed intake and body weight and affecting egg production. Air temperatures of 100°F (37,5°C) and more can be lethal for poultry.

Next to high temperatures, humidity is also an important factor when dealing with heat stress in chickens. So it is critical to monitor both temperatures and humidity levels during summer.

When using misters inside the coop or barn, please check the humidity level; it should never exceed 50%.

Can heat kill chickens?

Yes. In rare cases, heat stress, followed by a heat stroke, can cause death.

When a chicken cannot cool down its body temperature by seeking shelter or drinking, she’s in imminent danger. A chicken’s normal body temperature is around 104-107°F (41-42°C), but in hot conditions and lacking water or shade, they can’t regulate their body temperature.

A body temperature of 114°F (46°C) is deadly for a chicken.

Signs of heat stress in chickens

Panting, rapid breathing and fluffed-up wings are the most common signs of heat stress in chickens. It means they’re hot and need to cool down, but there is no need to be alarmed immediately. Just provide plenty of shade and cool water, and they’ll be fine.

During average ‘room temperatures’ between 65°F (19°C) and 75°F (24°C), a standard respiration rate of a chicken is somewhere between 20 to 60 breaths per minute. Temperatures above 80°F can increase this up to 150 breaths per minute. Although panting helps them regulate their body temperature, studies show it negatively impacts egg production and egg quality.

Severe heat stress should be dealt with immediately. You can recognize extreme heat stress in chickens by:

When noticing any of these symptoms, your chickens are having trouble cooling themselves and need help. Temporarily relocate them to a cooler area, submerge their feet in cool (not cold) water or try to cool them down by holding a damp, cool towel against their comb.

Can chickens sweat?

No. Chickens have no sweat glands. They rely on their respiratory system to cool down; they breathe heavily or begin to pant.

We’ll show you how heavy panting looks in chickens:

Things you MUST do to Keep Chickens Cool

  • Provide plenty of cool, clean water
  • Give them shady spots
  • Ventilate the coop
  • Provide dust baths
  • Clean out the coop regularly

Provide cool, clean water

It’s stating the obvious. Water is essential for any animal, especially during a heatwave. Chickens prefer cool drinking water over (luke)warm water, so try and replace it at least twice a day when the weather is hot.

If you live in a dry climate with long hot summers, consider collecting and preserving water to prepare for water shortages. Make sure there is always enough fresh water available for a refill. If the drinking water temperature is too hot, chickens might stop drinking at all!

Give them shady spots

When feeling overheated, chickens search for immediate shelter, so it needs to be provided. Some chicken keepers cover the run with shadow cloth during hot summer months or relocate the flock to a more wooded area.

Ventilate the coop

Coop ventilation is always essential, but during hot weather, even more!

Chickens are breathing and pooping, making the air humid and increasing carbon dioxide and ammonia fumes inside the coop. Our hens will suffer from bad air quality. When you open the coop and smell ammonia, you need more ventilation by creating an airflow on top of the coop. By having ventilation openings on the top your chickens never sit in the draft but the ammonia fumes and carbon dioxide can be replaced with fresh air.

Provide dust baths

Whether it is hot or colder, chickens love dust baths. It’s the ideal activity to keep them happy, entertained, and clean! During a heatwave, provide enough dust baths in shady areas like under the chicken coop. As an extra, you can wet the chicken run ground and make them a mud bath instead of a dust bath, so they can keep themselves cool by kicking the wet dirt on their feathers and skin.

Clean out the coop regularly

Cleaning out the chicken coop isn’t a popular chore, but chicken poop can easily smell like ammonia during hot weather, which makes your chickens suffer from bad air quality. If you’re using the deep litter method inside the coop, check the air quality regularly. Otherwise, the deep litter method can produce toxic ammonia gasses that endanger the welfare and health of your flock.

The chicken coop should never smell foul or smell like ammonia.

Things you CAN do to keep chickens cool

  • Ice their food/give cold treats
  • Ice their water
  • Wet the chicken run ground or/ and vegetation above and around the run
  • Temporarily keep them inside the house

Ice their food/give cold treats

You can feed your chickens regular healthy snacks like peas, yogurt, or corn, but frozen. Use a cupcake or muffin pan, fill it with their favorite treat like canned corn, and add water. Put in the freezer for 4 hours, and their tasty summer snack is ready.

Or hang a lettuce pinata they can peck or put some tomatoes and cucumber on a string. They’re mostly water, so they aren’t a problem for chickens.

But there’s a ground rule: don’t exaggerate. Never feed your chickens more than 10% of their total feed of the day in snacks.

Ice their water

Providing your flock with cool water mainly means it needs to be replaced regularly, not that you have to put ice blocks in it. You can, but it will probably melt very fast, so the benefit of cool water is only temporary. It’s always better to change their water at least twice a day during a heatwave.

Wet the chicken run ground or/and vegetation above and around the run

You can create your own ‘airconditioned’ chicken run by using the ground and surrounding vegetation as a natural barrier and moistening them. Hose down the chicken run soil a couple of times a day and spray water on surrounding trees or plants. This reduces the temperature inside the run and makes water trickle down from the trees.

If you don’t have any trees in your run’s surroundings, use a shade cloth to cover the run, spray with water, and create a micro-climate.

If you’re planning on using misters, only use them outside and not inside the coop or barn. Humidity is an important factor when dealing with heat stress in chickens. If the humidity in the coop is too high, the birds can’t downregulate their body temperature very well.

Temporarily keep your chickens inside the house

Keeping an eye on your chickens during a heatwave 24/7 isn’t possible when you’re working all day. Temporarily putting the birds in a garage or storage area can be an option to consider.

Of course, that’s not an ideal situation. First of all, chickens poop a lot, so prepare yourself for serious cleaning when you come home from work. You can train your chickens to wear a chicken diaper, but even diapers need to be taken off at least twice a day for an hour to prevent irritation. Furthermore, chickens need outside space. They aren’t meant to be kept inside, but it shouldn’t be a problem for a short period.

What NOT to do to cool down chickens

  • Spray your chickens with a hose
  • Provide a water pool or bath

Although chickens aren’t scared of water, they’re not particularly fond of it.

Chickens’ feathers are water-resistant and work as a raincoat. So spraying them with water won’t cool them; you’ll have to soak them to get the water to their skin. It’ll just give extra stress. They don’t like water baths either.

Providing them a kids pool to cool off in won’t do the trick either. Maybe they’ll splash their feet in it, but most chickens avoid wading through water. When not replacing the pool’s water frequently, it won’t be sanitary anymore and can be a hotbed for bacteria.


Chickens are very capable of regulating their body temperature, but during scorching hot temperatures, they can use some extra help. Always provide plenty of cool, clean water and enough shade spots so your chickens can cool off. Cleaning and ventilating the coop is essential to prevent your hens from suffering bad air quality.
