I bought one of my hens in as she was hunched and very lethargic. I gave her mineral drink and done the usual health checks, I can’t seem to find anything wrong. She picks up when warm but seems to deteriorate when she goes back out, it’s been a week of fetching her in and out. How long is it ok to keep her in and out of the flock. I’m worried about the extreme temperatures when she goes back out. Any suggestions?
