We have our first chickens and are experiencing feather pecking. I've tried several things I've read about, and am now at the point of considering if I need to re-home some hens. I'm hoping that the BYC community can share advice about and experience with my situation. Ideally we would keep all our hens. They are all very nice and my daughter, their caretaker, is attached to them. We have a flock of 5: 2 Golden Laced Wyandottes, 1 Silver Laced Wyandotte, 1 Buff Brahama, and 1 Light Brahama. Birds are 10 months old. We've had them since day 2. Coop is 3.5 x 4.5 (excludes nesting boxes). Run is 4.5 x 10. They free range for 5-6 hours a day. Feather pecking probably started around when they began to lay. I think it's been going on for 2.5 months. Based on eating it looks like pecking order is 1) Buff Brahama (also, gives everyone except #2 pecks on the head to keep them in line. Somewhat aggressive.), 2) Light Brahama, 3) Silver Wyandotte, 4) Golden Wyandotte 1, 5) Golden Wyandotte (the omega). The first 3 hang together, especially the Light Brahama and Silver Wyandotte. The Golden Wyandottes hang together, but the omega is always chased off food by the #1 and #3. The omega sleeps in the nesting boxes, even with extra roost space. The worst pecking is to the Silver Wyandotte. The two Brahamas are also significantly pecked. Pattern of pecking is the same on all 3: bare bottoms and spot on back of head, and missing feathers on sides. No blood has been drawn. It's only pulling feathers. They must be eaten because I find few. Golden Wyandottes are only pecked above their tail feathers. Bottoms and back of necks are completely feathered. I've seen the omega peck everyone on the back of neck or tail. I've seen her peck in the run and ranging, but I think most happens in the enclosure. Outside she has more to do. I've tried Pinless Peepers for 2 weeks and an apron for the Silver Wyandotte for a week. She did have back feathers growing in and the apron didn't prevent them from getting pecked. Plus she kept trying to run away from it so it was more like an annoying cape. I'm spraying bald spots with Blu-Kote. Last night I separated the Silver Wyandotte in a dog crate, but it's not ideal for space. Thanks for your suggestions!
