Hello, I just checked on my young flock and I found my 6-7 week old Dominique chicken with a drooping neck, feathers fluffed out, lethargic, green & white poop. She just went again and it was liquidy. The heat index in Georgia where I live is extremely hot, but all the other chickens are fine, only one had her mouth opened. They’re located in a shaded area by trees and the run is also covered. I put corid in the water right away just in case but I’m trying to think what else to do. If it’s heat stress related what can I do? or wry neck? Vitamins, electrolyte water?
