I have a welsummer rooster-He is with a few buff orpingtons, several white rocks, and a blue laced wyandotte, RIR,and some sorta black hen with some green in her ??? Will this cross make anything?? I have them in the bator-very few are white-most are dark or medium tan eggs. Just wondering what kind of color combo I could come up with. The eggs are so large-they barely fit into a normal egg carton- The black hen is lying eggs almost as dark as copper marans- I kept quite a few of those.
