Any suggestions on keeping chickens cool? I have 7 that live in a large barn in the lower section, which stays kinda of cool with the dirt floor and the shade. They also free range and sometimes hangout under a large pine tree. However I found my largest rooster this morning laying on the floor panting. I put him in the basement in a dark area where its much cooler and he improved almost immediately. I put a bunch of ice in there water containers. Any other suggestions?
