Keeping Chickens Happy in Hot Weather

The sun is the greatest threat to confined chickens, particularly in cramped or poorly ventilated areas. In hot climates like Phoenix, where temperatures can exceed 115°F, taking extra precautions is vital to keep your flock healthy and comfortable. When chickens become stressed or overheated, they may develop behavioral problems, reduce egg production, stop laying entirely, or, in severe cases, suffer fatal consequences.
Here’s what you can do to keep your chickens happy and healthy this summer:

Suitable Housing

Meeting the basic needs of chickens during hot weather isn’t difficult. With a little planning and effort, your flock can stay comfortable and healthy even in extreme heat.
One of the most critical factors is adequate space. Overcrowded housing drastically increases the risk of heat stress and can lead to aggressive behaviors like pecking, bullying, or piling, which only make the situation worse. Even if your coop has some shade, cramped conditions trap heat, reduce airflow, and create a dangerous environment.
Ventilation alone isn’t enough if birds don’t have room to spread out. Ideally, each chicken should have at least 4 square feet of indoor coop space and 8–10 square feet of outdoor run space—more in hot weather. This extra space allows birds to distance themselves from one another, reduce body heat buildup, and access cooler areas.
If your coop is undersized, the simplest and most effective solution is to build a spacious, secure run around it. Use shade cloth, trees, or other cover to protect the run from direct sun, and ensure the area has good airflow. Even temporary fencing can help provide relief by giving the birds more room during heatwaves.
In hot weather, space isn’t just about comfort—it’s about survival. The more room your chickens have to move freely and access shade and fresh air, the better their chances of avoiding dangerous heat stress.

Coop Location, Shade, and Providing Comfort

Chickens need access to shade. Observe how the sun moves throughout the day and ensure their coop and play area have shade in both the morning and afternoon. Keep their water out of direct sunlight and refill drinkers with cold water in the afternoon. On especially hot days, freeze a chunk of ice and place it in a shallow water container to help keep them cool.
Familiarize yourself with artificial shade options like shade cloth, shade sails, and my personal favorite—grommeted mesh shade tarps. Avoid using waterproof tarps, as they block airflow, which is essential for your birds’ well-being.
Chickens naturally cool off by digging into the dirt, so it’s important to provide them with access to bare ground. A portable mister can also be incredibly helpful. Position it high enough so that the mist cools the air without soaking the birds.
If your chickens free-roam, a damp area beneath a shade tree or low bush can become a perfect oasis. Try digging a shallow hole and letting a hose drip slowly into it. On particularly hot days, flood the area about an inch deep. Your chickens will stay cool and entertained as they search for worms and insects in the moist soil.

Warning Signs of Physical Heat Distress

A common sign of heat stress in chickens is a change in behavior, such as bullying, pecking at one another, or pacing. When overheated, chickens often hold their wings away from their bodies and pant—or do both simultaneously. More serious and dangerous signs of heat exhaustion include lethargy, pale combs or wattles, disorientation, and stumbling. At this stage, it’s crucial to act quickly.
The best immediate response is to submerge the bird in a large bucket or tub filled with warm (not cold) water to help gradually lower its body temperature. Afterward, place the bird in a shaded, preferably grassy area, separated from the rest of the flock. If possible, set up a fan to increase airflow around the bird. However, avoid bringing the chicken indoors—even if it’s cooler—as the sudden temperature change can cause additional stress.
Early Warning Signs of Heat Distress:
Panting or open-mouth breathing
Holding wings away from the body to increase airflow
Reduced activity or restlessness
Increased water consumption
Reduced feed intake
Pacing or agitation
Spreading out on the ground or stretching out legs and wings
Pale or shrunken combs and wattles

Quick Fix Fluids for Heat Distressed Birds

An excellent source of hydration on a hot summer day is watermelon! If you have a large flock, simply cut a watermelon in half, place it on the ground, and let them feast—they’ll pick it clean and love every minute of it.
Another helpful option is to add electrolytes to your chickens’ water. You can find electrolyte supplements at your local feed store, and they provide an extra boost to help your flock stay hydrated and healthy during extreme heat.
Smart Feed Choices in Summer: Scratch feed should be avoided during the summer months. Most scratch mixes contain a high amount of corn, which is considered a “hot” feed—it generates extra body heat during digestion. This added heat is the last thing your chickens need when they’re already struggling to stay cool. Instead, focus on providing fresh, hydrating foods and cool, clean water to help them beat the heat.

Best Bedding for Chickens in Summer

Sand: (Clean, Construction-Grade)
Why it’s ideal: Sand stays cooler than other bedding types, drains well, and doesn’t retain moisture, which helps control odors and bacteria.
Benefits:
Doesn’t harbor parasites easily.
Easy to clean with a cat litter scoop.
Reflects heat away rather than trapping it.
Pine Shavings (As a Secondary Option)
Note: Pine shavings are absorbent and offer a clean, low-dust environment, however, shavings can retain heat and moisture, so use a thin layer and stir or replace regularly in hot weather.

Bedding to Avoid in Summer

Straw of Hay: (When Damp of Deeply Layered)
Why to avoid: Straw and hay can trap moisture and heat, creating the perfect environment for mold, bacteria, and ammonia buildup. This can lead to respiratory problems or heat stress. Especially risky in deep-litter systems during hot weather.
Cedar Shavings:
Why to avoid: Cedar emits strong oils and fumes that can irritate chickens’ respiratory systems, especially in hot, enclosed environments.

Keeping Chickens in Excessive Heat

Recipe for Survival

Once again it’s that time of year when soaring temperatures raise concern for chicken keepers. For those who can free-roam their flock there is less worry. But if you have backyard chickens that are confined to a coop, your worries are quite valid. Here’s what you can do to make your flock more comfortable.

Air Flow

There are steps to take that will help your chickens beat the heat, but it will take a little effort on your part.
If your coop is overcrowded it’s time to expand, too many birds in small quarters is just asking for trouble.
Air flow is vital. Chicken droppings generate heat, so be sure to clean the coop and lay down fresh bedding. If at all possible provide a fan for ventilation,  if it isn’t… find a way. A fan could be the difference between life and death.
Keeping the Flock Hydrated
There is a pecking order among chickens, so provide extra water sources for those lower-ranking birds who might not be allowed to use the drinker.
Chickens will drink more if the water is cool, provide cool water at the hottest time of the day. If you have broody hens, make it easy for them to access water, don’t assume they are leaving the nest… some don’t.
Tip: Full buckets of water will stay cold longer, put out a few.
Shallow ground drinkers work nicely for bantams.

Electrolytes

It’s always a good idea to have electrolytes on hand for those really hot days. Simply add it to your flock’s water source. Electrolytes for poultry can be found at your local feed store. It comes in many forms, choose one best suited for your needs & the size of your flock.

Chickens may or may not like a mist system, my birds hate them, however, I have heard positive feedback from other chicken keepers. So it may be something to consider useful in dry climates.
A more positive approach is to provide your birds with a small flooded area for them to play in. Even if it’s just a hose allowed to drip, they are magically lured to this life-saving man-made oasis.
Triple Digit Temperatures
Here in Phoenix, our temperatures can reach 115+ degrees, this is when it’s time to bring out watermelon, cantaloupe, lettuce, or anything that will help hydrate the flock. These foods will be better for them than layer pellets containing corn, which produces even more unwanted heat.
During these heat spells, I ration layer pellets, offering in morning, mid-day, and night for about an hour or so.

Recipe for Successful Chicken Keeping in Excessive Heat
Shade is essential to the survival of chickens in extreme temperatures, especially if they’re cooped.  Your coop is best placed under a shade tree, but remember the sun moves and may leave your birds exposed to direct sun during the day.
Never use tarps
Shade cloth, mesh tarps, and shade sails are excellent for keeping the sun out, yet they don’t restrict airflow. Shade cloth is cheaper than mesh tarps and is available in most garden centers. Mesh tarps might be pricey, but they’re a lot easier to hang. Both, are durable and offer long-lasting wear.
Offer watermelon or cantaloupe & place it in a shady area.
Find a way to hang a fan a foot or so from the ground.
Provide an area where a hose is on a slow stream or drip.
Keep drinkers filled with cool water. Tip: Buckets kept full will stay cold longer.
Use shade cloth, mesh tarps, or shade sails.
