I posted a few weeks ago about some pecking behaviors and things have gotten worse. I am a new chicken owner, have 4 chickens in the city in an enclosed run. We have had some pecking injuries and bare spots from pulled feathers starting in early Feb. We tried many things over the last couple of months including saddles and nose clips and cabbage and suet block and separating them for weeks and nothing helps for very long. We even built a tiny timeout coop to keep the problem chicken separated in but now they're ALL problem chicken! We went on vacation last week for a week and came home to all four chickens now having issues. The shy one is now the bully and has pecked bare spots on 2 other chickens, bare legs/thighs. We have now separated all four chickens and have run out of ideas as to how to keep any of them in the same run anymore without them killing each other. We just got another snow storm and I believe the combination of not enough space and a long, nasty winter in Michigan led them to these issues. I just don't know if there's any fixing it at this point? I've read all the articles and tried just about everything I can in a suburban backyard in winter.
