Hello, This is my first thread, so hi everyone. I am at my wits ends. I have 7 buff orphs and 6 black austr. and they were born oct. 1 '13. They are just now coming into laying, some for a few weeks, but I have one who is in isolation for the second time. She, or mama, was bullied when she was a 6 week old chick. I separated her and she came back good as new. Only now she has caused nasty injuries to my other buffs, one with a comb half ripped off and the other the neck ripped open. The one with the neck injury healed well, but the injured comb one keeps tearing it open again. She is separated again, and will heal completely before I put her back in. Mama had been separate for 5 days, and I reintroduced her. Within an hour, she was back at it, grabbing and ripping at all the other birds' combs. She is so vicious, and I have called a neighbor to see if she will take her. Any advice on any other options? She is the most mature, follows me around the yard, and is so sweet to humans, I would hate to cull her. But I cannot reintroduce her. She leaves the australoupes alone, but the buffs are constantly in defense and hide mode. Thanks ahead of time.
