So my older flock has 9 hens and 1 roo. Last summer I tried integrating a barred rock in with them and they pecked her like crazy. She seemed ok after a bit and when we went out one day after work, she was near death because they'd attacked her that day and really did a number on her. I figured it was because they were intimidated by her as she was bigger than most of them. She ended up dying shortly after we found her even though I rushed to get her out of there - it was too late. I felt awful. Fast forward to these past few weeks. I had a grown buff orp and we put her in a big cage next to them for a couple days so they could get acquainted at a distance. Things seemed ok. At nightfall, we put her up to roost with them and checked in the morning. She really didn't want to leave the coop. A few days in they were pecking her occasionally l, trying to establish order but it wasn't anything abnormal. By a week in, they'd really started to get worse and pecked a red spot at the back of her head. We put blue kote on it. My husband even held he rawhide and sat down with her and anytime any of them came up to peck her, he'd shoo them and protect her. They seemed to chill out after that but she mainly continued to hang out in the coop and would rarely go out with them. They seemed to leave her alone that way. So now today, I go out there after getting the kids from school and find her in the coop, one eye shut and painful looking and her comb bleeding, all the feathers torn off the back of her head...she was a disaster...laying on the floor...& she's been in with them nearly 3 weeks and now this all of the sudden??? I grabbed her and set her up in our shed in her own big cage for now. Didn't do much doctoring yet because it was getting dark and I didnt have anything with me. I have decided I will not EVER return her to that flock and I'm really concerned I maybe need to break that flock up now. I'm sure they would have killed her if I hadn't saved her today. I'm still worried she might not be ok. I put fresh bedding, a nest box, food, water and her favorite treats in the cage in our shed. I'm hoping she can rest tonight and I can get a better look at her tomorrow and do any doctoring that may need to be done. I hope she doesn't lose her eye. :-/ I've decided if she pulls through, she'll be the mama and head honcho of the chicks as they get older because she's very sweet and maternal. But has anyone experienced this??? The flock continuing to attack any newly integrated chicken until they practically or DO kill it?? I'm shocked they've been so horrible. Pecking order and even some nastiness I get - but this just has me floored andnot makes me want to rehome half the flock at least...or cull them. Any help or ideas? Thanks in advance!
