I was concerned this yr about heat. We live in Fl. My coop is small. I have 6 16mo old Buff Orps and 3 Ameracauna. We thought about a bigger coop, but the girls are only in for sleeping and laying. My husband put wheels on the coop when we put it together. We keep the coop where it gets max shade during summer. My husband got round soffit vents 4" . They have slanted grates and screen on them. We put in 4 using 4" hold saw. 2 up high across from each other just under roof point. 1 near nest boxes and 1 low on large access door. These give more air circulation in the coop. save the wood rounds to put in during winter or storms. We leave coop door open 2 4/7 but lock the run every nite. My girls free range from 7am till dusk every day. I keep a 4 qrt waterer hanging under coop and a 5 gal out in the yard in shade. I only keep 2-3 gal in it. Too heavy to move otherwise. It has a large opening. When the water starts to get warm in the shade, I put a frozen water bottle in to cool it down. At the end of the day rinse the bottle n put back in freezer. You can use muffin tins and put unsalted, rinsed can corn in the cups, add water to fill cups n freeze. Pop them out when froz. Store in zip lock bag in freezer. Put few out each afternoon. Hens will peck ice and eventually eat the cold thawed corn. I buy a small watermelon each week and cut into triangles n store in zip locks. Take a few pieces out in the heat of the day. My peeps love it. Cantaloupe too when on sale. Both usually reasonably priced. Refrigerate leftover rice or pasta. The next day add some plain, non fat yogurt. 2Tbls, they love it! I do cut up long pasta so no crop issues. Not every day though. They get yogurt couple times a wk. You can do the same with oarmeal. You could also use applesauce in the muffin tins. You don't say where your located. Can you run a sprinkler for hour or so near or on part of the coop to help cool it down? Good luck!Hi everyone! I have six pullets who have moved to their coop a few days ago. The temperatures are really getting high and I'm a little out of ideas. They are panting, and laying down a lot. I have a frozen banana I will feed when it thaws out, frozen water bottles, a tiny wading pool, extra shade, and ice cubes in their water. I'm a little worried because they are peeping a lot. They are still eating their feed, which I am probably going to freeze. Are there any other ideas? Also, has anyone tried putting a bowl of ice cubes for them? Would it cool down the air around them?
