Out where I am it was about 95 in the shade. What I do is I go out a few times a day with a spray bottle and mist them with cool water. My one rooster loves it.

Unfortunately, last week, I Horribly and accidently, lost one of my girls, a 1 yr old Barred Rock, when, to the best of our knowledge, slipped into the duck's kiddie pool, that she has been raised around since she was a chick..
My son found her when he went to let them out of their coop in the morning.
We are just now really able to talk about it, and I just hope that my chicken friends are very careful of having kiddie pools around chickens...its a horrible feeling..
