A couple of days ago I came home to find that the RIR hen I adopted from my sister had lost a lot of feathers that were all over the run. I first thought that some of the other hens were responsible as she is the "newbie" and the pecking order was still being established, although there were no wounds visible. So I separated her from the rest of the flock again thinking this would take care of the problem. But it hasn't and she is going bald! If anyone has any ideas on what could be causing this I would appreciate it. She was beautiful and healthy when she came about a month ago. I kept her separated for a week and the first two weeks went okay with the hens together. Thank you!
