My 6 week old chicks have a bad habit of pecking each others feathers and breaking them off, then eating them. It started when they were too crowded in the brooder (I know, it's all my fault) and we hadn't QUITE got the coop finished. Now they have plenty of room and free range in the fenced yard during the day but still they are breaking off and eating those feathers. What can I do to stop this really bad habit? I think I read once in on BYC about how to stop it but I can't quite remember....is there something I can put on them so the feathers taste bad or something? Help, all those beautiful new feathers are being broken and eaten!
