Still trying to wrap my head around all of this . . . I pretty much get the percentages and how to get them, but here is yet another question from me The hatchery near me (Dunlaps) sells their own cross they call Austra Whites; they use a Black Australorp and and a White Leghorn. Most of them turn out to be what I think is called splash; mostly white with a few random black feathers. My question is this: If I bred those birds back to a black (of any breed) would I get all blue offspring?
