The temperature I've read that chickens start to be in danger of overheating is 90 degrees. There is a major heatwave that is pushing the heat index past 100 degrees! So I was wondering if anyone had tips on keeping chickens cool because I do have two Buff Orpingtons that are starting to molt a little because of heat stress. Imagine wearing a winter coat in over 100 degree heat! Whew, makes me sweat thinking about it. My chickens are free-range and don't like getting wet anywhere except their feet so I've been filling a pan of water and setting it on the ground for them to step in. Most of them don't step in it but one of my two Silver Laced Wyandottes will put both feet in the pan and actually start scratching in it as if it were dirt. I've also been feeding them cold watermelon. All tips and ideas for keeping chickens cool will be greatly appreciated!
