No rosters. Definitely not overcrowding. Egg laying is good so don’t think they’re stressed. We have had a long stretch of rain, hot, humid weather, but nothing really unusual .
We have ten chickens in a pretty large coop. Recently we have most of them showing feather loss along their backs near the base of their tail feathers and around their butt/vent. Any ideas on what’s going on? Other behavior and egg laying is normal.
