Last summer I had, what was once a friendly hen, Myrtle, viciously attacked another hen, Baby, in the flock. Myrtle had twisted neck months prior to the attack. She was separated for several days until she recovered. When I placed her back with the flock she moved up in the pecking order.
Months went by and then out of nowhere, Myrtle attacked Baby. There were roaming free when it happened. Baby wanted to fight back but I got into the middle of it because I truly thought they were going to kill each other.
There were four hens in the flock and they were all raised together from chicks and they have always gotten along (they will all be seven years old this year). The attacks continued. Myrtle would go out of her way to bite Baby. Even Baby's best hen friend, Cinnamon began to alienate her. Sadly, Cinnamon passed away last Fall, so now there's only three hens in the flock. Weeks later I removed Myrtle from the other two hens for a few days thinking that the dynamics of the flock would change once I reintroduced her, or at the very least, Baby and Bella would become closer. The two did become closer but once I placed Myrtle back in the flock, Baby was alone again.
Baby spends much of her time alone. She roams the yard alone, roosts at night alone.
Is it possible the three can be friends again? Please, any suggestions on what I can do to make life better for Baby would be greatly appreciate.
