I have read that black skin is dominant when bred to other colors. How does it work in the next generation. For example, sumatra rooster bred to BBred game hen produces black skin/faced young. If you use one of the roos from that cross and cross it back to game hen will you get 50% black 50% normal? (mendellian dominance) or is it then incomplete dominance? A bunch of black faced birds with red bleeding through?
