Today I sat and observed my flock of 7 hens and 1 roo. Everyone except one chicken has bald spots. No it is not from mites I have looked them over really good and dust them regularly with 7 dust and DE. I have witnessed the BA's pulling out feathers. I had all 8 of them in a 4x8 coop with an attached 16x10 run and I let them free range every afternoon for about an hour so I don't think space is an issue. I feed them layena pellets with egg shells mixed in for extra calcium. They get greens and cracked corn for treats along with other kitchen scraps including shrimp shells and leftovers I do not give them scraps everyday so I do not think diet is an issue either. SO today I watched them to see who the feather plucker might be. In the past I only witnessed one but now it seems that all 3 of my BA's are plucking feathers. So I isolated the 3 BA's in a 10x10 dog kennel secured with 4' 1/4 x 1/4" hardwire cloth around the bottom. I am hoping if I disrupt the pecking order then this behavior will stop. I really don't want to put pinless peepers on them. My question is how long do I need to seperate them from the group to effectivly disrupt the pecking order? Also how long will it take my other girls and roo to regrow their feathers? (The poor roo looks like a naked neck chicken, my Delaware has a bald butt and one of my EE's has a bald back.) If you have experienced this problem before and have any words of advice please help. Thanks!
