My poor babies are out there panting and I feel so sorry for them. I've opened the windows all the way and I put a small battery operated fan out there to push the hot air out and help draw cooler air in. I put a large pan with ice water out there for them to walk and play in. An they have constant access to the outside if they want it. I have a tree that shades the run but not the coop. I'm thinking of running an extention cord and putting in a larger box fan instead. I just feel so bad I want to buy them an AC unit, if I had the money, I'd do it too. It's about 100*F out there. What are all of your suggestions for keeping your chickens cool?
