Good morning all, I need some advice. I have 8 hens a little over a year old, all raised together since day 1. 3 Reds, 3 barred rocks and 2 Araucanas. They are caged while I'm at work in a VERY spacious, well thought out pen, and then free range from. 3 days ago I noticed that one of my reds has a bald spot on her head indicating she may be getting bullied a bit. They have always gotten along and I've never noticed any violence until yesterday. There were 2 occasions where I had to break a fight up between her and 2-3 hens that were brutally attacking her. They had her pinned down twice and had I not intervened I feel like they would have killed her the second time. She was pinned in a corner with 3 of them on top of her attacking. I've never seen anything like it! I have separated the bullied hen and made sure she has no serious injuries but am at a loss of what to do from here. I have been reading and see that this behavior could subside or it could get worse and she is in danger... Any advice would be greatly appreciated. I am really worried about her. This came out of no where! Thank you for your time.
