Hello, I have a hen who is bullied by the other hens so I isolated her for several weeks so her feathers on her back could grow back. It looked to me like the feathers were growing back nicely so I let her out. My mistake, I should have stayed to watch, and the other hens pulled out all her new feathers. I've heard the shaft is an open blood vessel and that when chickens get the taste for blood it's hard to stop them. My 2 questions are: Should I have waited for the feathers to grow out all the way, as opposed to about an inch? Since many of the shafts are still in place (but feathers removed), will the new feathers grow back more quickly? Needless to say, I put the poor girl in isolation again. Appreciate any insight.
