This is a new experience for me. I have been raising chickens for a couple years now, but I have a new Buff Rock who is picking at her new tail feathers and has nearly plucked all of them out. I put the 4 week old pullets into a larger brooder, but I am not sure why she keeps doing this. Should I just put some wound salve on her tail and hope it will deter her from further destructive pruning? I will try to take a picture later.
