I'm not sure if I have a hen plucker or preener. My buff orpington (lowest in pecking order) constanly pecks at the other hens - and they let her. One in particular seems to like it. I suspect she's doing it for the reward--feathers! Should I remove her for a couple of days or just let her do her thing? One head hen has a bare bum, partly from the plucker and partly from a physical problem I had with her months ago. I spray her tush with the purple stain and there are no open sores but the feathers don't have a chance to grow back. I have 5 hens, their run is about 100 sqft. Diet: manufactured crumbles, one cup of scratch in morning, 1 cup of BOSS in the late afternoon, wheat grass, yogurt.
