I have two hens fighting over the same clutch (2) eggs. My little catalana has been sitting these eggs since Saturday. When I checked on her today my seabrite had run her out of the nest. There also appears to be a bantam egg in the nest, but don't know who it belongs to. When Belle tries to go back the seabrite pecks her and is very nasty. She is so upset, pacing and clucking. I took the seabrite out and put Belle back but don't know how long that will last. Any suggestions?
