I have a white drakelett. He's not fully feathered yet and completely white, no cap. His parents are mother and son: Mother - black/white magpie Her mother- Black. Her father - white. Father -blue/white magpie. His mother - the duck above. His father - silver I know the blue is dominant, but I'm unsure how it works against whole white. Does this white drake have the dominant blue gene? If I breed him to a black female, will his offspring be black or blue (with white)?
