When the weather gets really hot, chickens can get uncomfortable—and even sick—if we don’t help them stay cool. Whether you’re new to raising chickens or just need a refresher, here are some easy, effective tips to keep your flock safe in warmer climates or a heat wave.

🥵 Why Heat Is a Big Deal for Chickens

Chickens don’t sweat like we do. When it gets hot outside—especially over 90°F—they can start to struggle. At 95–100°F and above, chickens are at risk for heat stress or even heat stroke, which can be dangerous or deadly if they don’t cool down quickly.

The key elements for helping your chickens beat the heat are water, shade, and ventilation. Here are some tips:

💧 1. Make Sure There’s Plenty of Water

Chickens drink a lot more water when it’s hot. On a normal day a healthy laying hen drinks about 1 pint (16 ounces) of water per day. On a hot day, however, that amount can double or even triple, with hens drinking up to 1 quart (32 oz) or more, depending on their size and activity level.

• Add extra waterers so they don’t have to wait in line.
• Keep water in the shade so it stays cooler.
• If you can, try an automatic waterer to make sure they never run out.
• Add ice cubes or frozen chunks of fruit to their water to keep it cool.

❄️ 2. Freeze Treats for Hot Days

Cold snacks help chickens cool down from the inside out, similar to how cold drinks help cool humans. Many frozen treats have a high water content, which helps keep your flock hydrated—a key to preventing heat stress.

• Try freezing their favorite treats such as watermelon, berries, or even corn and greens.
• Mix kitchen scraps into a bowl of water and freeze it for a homemade chicken slushee!
• Serve treats in the shade to keep them colder longer.

💨 3. Keep Air Moving

Hot weather isn’t just about temperature—it’s also about airflow. When the air inside a chicken coop isn’t moving, it can cause serious problems for your flock! Chickens can’t sweat, so they rely on panting and air movement to cool off. In still air, moisture sticks around, making it harder for chickens to regulate body temperature and increasing the risk of respiratory issues.

• Use a portable fan to move air near the coop.
• Point it across a bucket of ice to make the air even cooler.
• Never aim fans directly at roosts—they should feel wind, not a blast.
• Use cross-ventilation to move hot air out and fresh air in

🌿 4. Expand the Shade

Shade is a must in the heat. Well-placed shade can lower the temperature by 10–15°F compared to areas in full sun. Aim for at least 4–5 square feet of shaded space per chicken in the run, however, more is always better! Chickens spread out when it’s hot and will avoid crowding to stay cool.

• Move patio furniture, plants, or umbrellas near the coop.
• Drape shade cloth, burlap, or breathable old sheets over the chicken run.
• Even cardboard or old sheets can help in a pinch!

🛁 5. Create Dust Baths

Dust baths help absorb moisture and oil from chickens’ skin and feathers, which helps them feel drier and more comfortable on hot, sticky days. In summer, make sure their dust bath area is in the shade and has dry, loose soil or sand. You can even add a little diatomaceous earth or wood ash to boost parasite protection.

• Chickens often dig their dust bath spots in shady, cooler soil—which gives them a cool place to hang out.
• If they haven’t made one, add a tub with loose, non-homogenous sand and/or clean dirt.
• Dust bathing is also calming, so it helps reduce heat-related stress. Add dried herbs such as lavender or chamomile to boost this stress relief.

💦 6. Use Evaporative Cooling

When water evaporates, it pulls heat from the surrounding area. This cools the air, ground, and surfaces nearby. Spraying or misting dirt or sand in the run helps keep the ground cooler. As chickens walk or lay on damp soil, they absorb coolness from below (without getting wet). If you use a mister or light spray in an area with airflow, the moving air spreads that cool, moist feeling—kind of like a natural A/C for your flock!

• Spray down the ground in the morning with a hose or sprinklers.
• You can also use simple hose misters during the hottest parts of the day or turn them on intermittently, like the Orbit Sidewinder, for under $10.

💡 Pro Tip:
Only use evaporative cooling if your coop area has good drainage and ventilation, or it may just make things damp and muggy.

🐔 Hot Tip: Watch for Signs of Heat Stress

If your chickens are panting, holding their wings out, or acting very tired, they might be overheated. Act fast: move them to shade, cool them with water or ice, and offer electrolytes if you have them.

Electrolyte Recipe (DIY): Mix together
1 gal water
1 tsp baking soda
1 tsp salt
1 tbsp sugar
1/4 tsp potassium chloride (optional – “Lite Salt”)
