Will chickens that lay smaller white eggs sit on larger brown eggs from a different hen? I have Japanese Bantams and want to use them as surrogate egg sitters and mothers for my larger Sex Link Hens. My Sex links never sit on the eggs. My Japanese Bantams are new to my house hold and I just hope they will sit on my sex links eggs. The difference in egg size is about double or more. Will the Japanese Bantams still sit on them?
