Last week, our 12 week old girls ganged up on one of their own and picked and pulled out most of the tail feathers of one of their sisters. I separated the picked on one and she seems to be doing well. I also increased the space the other 12 have to relieve what might have been overcrowding. The injured girl seems to be wanting to join her sisters again but I'm a little concerned that she maybe picked on again due to the looks of the few tattered tail feathers she still has. This is our first flock so I'm unsure if I should trim back her affected feathers. Will her feathers grow back before she molts or will she be funny looking for the better part of a year? Any other suggestions?
