Are you agreeing that a blue wheaten roo X wheaten hen may result in a wheaten chick and that wheaten chick will not inherit white feathers due to the blue cross?
Blue x normal (Wheaten) always makes 50% blue based, 50% normal based.
They will not inherit white feathers in the sense of replacing the blue or black, no. But if we're talking unwanted white in places like primaries, legs, sure, it happens.
