I have 1 roo and 3 hens that are being a little mean to a new hen. I understand the pecking order and all, but I don't get why the roo is doing it. It's been 3 days, how much longer should I let it go? She is a June hatch that I kept (from the birds that are being mean), been in a cage attached to the main run (I call it my starter cage), so the birds have seen each other. HELP!!
