So i have two hens who will not leave the box. The two hens are bantam silkies, in the same box (which is about 1 sq foot) and there is nothing in there! I have been removing eggs whenever i see them, and still they sit there in a black lump and peck at me when i go near. Throw them out of the box, they go into the broody stance and hop back in after a few seconds. How do i break them?
