2 separate flocks of my chickens just moved into one cage and all except 1 want to pick on my EE. What should i do. All she wants to do is stay inside on the roost bar all day and when she comes out they chase her around the cage. Im so confused because she was once at the top of the pecking order. How do i stop it before it gets worse. Should i just close the coop during the day so she can't go in?
