Oh , I did not know that .
Thank for letting me know
Breed has nothing to do with the color, color crossing with other colors will have the same results regardless of breed. Lavender being recessive won't show unless both parent birds each carry the lavender gene. So, if you bred a lavender Marans cock over a lavender Ameraucana hen you'll get a lavender Olive egger but the plumage will be lavender as both parents carry the lavender gene. If the Ameraucana hen were black the chicks will be black, not lavender but bred to a lavender some will produce lavender and some black.
