The temperatures here are starting to get high and this summer we'll have plenty of 100+ days. We have a raised coop which the run goes all the way around. During the hottest part of the day right now the chicks all go under the coop in the shade and sleep. They're 8-11 weeks in age. I do have some heavy feathered breeds, I'm concerned about heat for the Cochin, the Faverolles, and the Buff Orps in particular. We're planning to build another shade structure inside the run. Basically a two by four stand with a sheet of wood or maybe tin roofing running at an angle down to the ground so they can either get under it or sit on top if they want. The coop door is open all day and when they start laying the next boxes are inside there. They are on the east side to minimize the hottest sun during the day. We do have trees planted, but they won't provide any shade yet this summer they are too young still. We put ice in their water the last two days when it got to around 90 and I have a tin pie pan I put ice in so the water melts and they can either drink it or go stand in it. I did see them drinking from both after we added the ice. I let them out in the yard with me when I get home in the evening and the first thing they did all week was run to my flower bed which is against the back of the house. The potting soil is cooler there than their sand and they all dust bathed in my flower bed. I didn't have the heart to run them off, not sure I'll be growing much there this year! So at night when they all go in to sleep I wet down the earth under the coop and in one corner of the run so the dirt would be cooler hopefully the next day if they wanted to roll in it. Not sure if that helped or not! Is there anything else I can do to help them stay cool?
