I just got 5 RIR layers from a friend of mine who is moving. A few of them are missing feathers/bald on the wings and back, above the tail. (These chickens came from a pen with close to 15 in it.) I noticed that one of the hens would peck at two of the others but it seemed to be only when they were trying to lay an egg. I know they were overcrowded in the pen that they came from but they are not overcrowded now. Will this behavior stop eventually? I currently have them in a run and trying to get the coop finshed in the next couple days so they will have more room and am hoping that once I get the nest boxes done that will help. The pen they came from was just a run and no coop or nest boxes. Any advice would be appreciated.
