I have been breeding my own version of these birds by crossing both Silver Laced Wyandottes and Black Australorp Roos with my Wheaten EE hens. I end up with these gorgeous blue birds or blue laced white birds. They are so pretty. I even ended up with a rumpless roo during one cross. My EEs lay a light green egg. My Olive Eggers lay a really pretty Khaki green egg, not as dark as some I have seen, but still pretty.
