Help!! I have a new flock ( they have been together since last Spring). I had one chicken from an old flock, but they have done well together up until the last 2 months. I'm wondering if it was the weather (we had a very wet and cold winter) but my previous flocks have never had an issue. I do have birds from multiple breeds. Anyway, about 2 months ago I noticed they were losing feather on their bum. And one had a deep peck wound. I removed the injured bird until it was healed , but then another bird got a peck wound. And I'm not talking a little peck wound, but deep to the bone on some of them. It took a month for them to heal up. I've spent hours and days reading and trying too figure out the cause. Plus I have no idea, who is the pecker. Pun intended!! ;( I"ve tried toys, and treats, and finally I did the Pinless Peepers yesterday. I went down today and one has managed to get her Peepers off and her bum is bleeding !! Aghhhh!! They can't really free range unless I'm out there, we have coyotes. Suggestions ?? How the heck did they peck with the Peepers on ?? Any constructive advice would be appreciated. Thanks!!
