I had the same problem last week with one cock bird. He was the only one that had the problem. Hosed him down, but left him with the flock to see if he'd make it. It was touch and go overnight, but he bounced back the next day.Came home to one of my Brahmas in full blown heatstrokeShe is cooled down and resting in the nice cool basement. Hoping she makes it through. Wondering why it affected her and no one else but I doubt ill ever know. Plenty of shade and fresh water....no wind today probably part of the problem. Darn weather!!
I've put some misters in the runs to help with the heat....
