We have two week-old Ameraucaunas and one of them constantly pecks/grooms the other. They are supposedly both hens. The victim doesn't seem to mind most of the time, but we are new to having chicks and wondered if this was normal for chicks so young or should we invest in some kind of product to keep them from hurting each other. They are in a rabbit hutch and cry when we separate them! We'd like to keep both of them and appreciate the feedback!
