I have a real problem! I have 6 hens that have all gone broody and are trying to lay on the same eggs. The nesting box will accommodate all of the hens so I put some eggs under each hen. Whenever an chicks hatches out of their egg, the hens kill it. What can I do?? I tried moving the hens to separate nesting boxes but they just will go right back to the original nesting box and sit on another hen if necessary. Any advice would be greatly appreciated! Thanks in advance!
