The coop we have for the girls has an inside and an outside, but they don't like being inside unless they are in the nest box. The outside has tall grass that helps a little, and we have some shade from above, plus loose dirt they can dust bath in. We also went to the home improvement shop and got the little misters that you can attach for a patio space. They aren't thrilled with them, but the water is so little that they don't get that wet and it drops the temp in the area, and that is more important. We have to have things that we can set in the morning and leave for the day, since we both work, and the mister is our main plan for those really hot days. (It's a trick that I picked up from the zoo, since they do it for humans and some of the animals.)
