I am aware of the genetics of blue, what produces what color. So of you breeders, what color are your roos? Do you keep a splash, blue, or black? Which combinations give you the best colors. Is there any difference in a blue from a splash and a black, or a blue and a blue? Do you keep only a certain color for your hens or roos, or do you keep all 3 colors? I guess in general, how do you manage your blue flocks?
