Hi, just trying to alleviate lockdown anxiety ...... If I were to put a Leghorn x speckled Sussex roo over a purebred speckled Sussex hen, would the offspring continue to exhibit dominant white?

Some will and some will not. Theoretically 50% will be carry dominant white and 50 will not carry dominant white. Even the ones that are dominant white could be white tailed reds or whites ( leaking black). It all depends on the number you hatch. You will get some variation in the color of offspring; black tailed reds, black tailed silvers, blacks leaking red and blacks leaking silver ( birchen and brown red looking).Hi, just trying to alleviate lockdown anxiety ......

he is Solid white(with black spots) because he is still carry the ER Birchen e allele and also carry one copy of dominant white...The roo is solid white, though only a few hours old, he has one black spot, and his neck is more reddish than the rest of the yellow fluff. And its a hypothetical because he could be a sheI really like the attitude of my Sussex hen, and she outproduces my other hens but her eggs are smallish. I thought a Leghorn cross might be less flighty, and lay larger tinted to brownish eggs. Then cross back to the Sussex for a rainbow flock next season.
First, trust Tadkerson much more than me. He is a recognized expert. I’m more of a rookie that guesses. I’m still trying to figure out how you can get a black hen but not a black rooster out of that cross. The only sex linked gene I’m aware of that could be involved is gold/silver and I don’t see how that could make a difference,
Birchen females can be easily melanized and look completely melanizedA Birchen female is black except around the head and neck while the Birchen male has a lot of other color in addition to black other than just on the neck and head. When I think of Birchen I think of the adult plumage and I just don’t think of a Birchen female as “black”. I think of them as black with a silver, yellow, gold, or red head and neck, depending on what else is in the genetic mix.
