I have a barred rock hen that hardly ever leaves the chicken coop. Im not sure why. She just stays in there all day. I feel bad, but I don't know what to do. I think she is worried about the roosters getting on her, but we only have 4 roosters and like 20-30 hens. Do old hens do this? She looks as if she could be a little older, but I think she's still laying. Anyways, I will post pics tomorrow, but for now does anyone know what could be wrong?
