I try to catch them on day one. Then give them a cool belly bath for about 2-3 minutes is all that is required. I just cool the hot belly spots back to a normal chicken temperature.
Charlie’s been broody for a few days so it’s probably going to take longer to break her. I’ve had conflicting advice as to whether to let her out or not. I hate the thought of her sitting in her own filth for days on end, or not being able to stretch her legs. But if letting her out is going to exacerbate the problem, I don’t want to do that either!
