Her set up is appropriate for 2 birds at the very most, and to be honest, I'd not consider using such a tiny space for ANY chicken(S). Chicken social structure can be brutal. And when a high rung lady/guy tells a lower rung lady to get out of his/her space, what the bird is really saying is this: "Get out of my space, (which is usually at least a 5' radius) or I'm gonna rip your face off." So, in a tiny coop, even if the underling does try to comply, she can't go far enough away to satisfy the social protocol. So, the top dog proceeds to mete out the discipline, and she/he is usually assisted by the rest of the flock.
