I have heard not to cross the Blue Americans and Buff Americans. So what happens if you do? What color would the offspring be? That "blue" in Americans, which is not actually blue, it's gray. is not a dilution on black like the blue in chickens and ducks. Isn't it a dilution on that buff color? There isn't any other color in Americans, is there? So it would have to be a dilution on the buff. If it is a dilution on the buff, and you crossed blues with buffs, wouldn't you get a mixture of blue and buff goslings?
