Cream legbar roo over barred rk hen will off spring be auto sexing?

[Ocho 8 Farm]

Is it possible for this combination to produce auto sexing chicks?

Also, what about same roo over buff orps and buff Brahma hens?

Oh, ok thanks so much

Cream Legbar rooster over Barred Rock hen:
Chicks should all be black with white barring. They should be just as sexable as pure Barred Rocks. Males have two copies of the barring gene (larger head spot, lighter feet, more white in their feathers as they grow). Females have one copy of the barring gene (smaller head spot, darker feet, less white in their feathers as they grow.) You should be able to make a good guess about male vs. female, but there may be a few that are just not clear and you'll have to wait until they grow a bit.

Cream Legbar rooster over Buff Orpington hens and Buff Brahma hens: not possible to sex by color. All chicks will inherit barring from the father. All chicks will have some amount of gold/buff color, and probably some amount of black (more black in the Brahma-mix chicks, less black in the Orpington-mix chicks).

If you hatch all the eggs together, you can probably tell which chick has which mother after they hatch:
--chicks from the Barred Rock hen will have large amounts of black. Chicks from the other hens will have yellow/gold/brown/red shades of down instead of the black.

--chicks from the Brahma hen will have feathered feet and pea combs. Chicks from the other hens will have non-feathered feet and single combs.

--chicks from the Buff Orpington hen will not be black (Barred Rock mother) or have feathered feet (Brahma mother.) They should have white feet, while the other two sets should have yellow feet (Brahma mother) or yellow soles (Barred Rock mother.) The foot/sole color will probably be more obvious after a few weeks, rather than right away. You will probably have them figured out by down color & foot feathering before the foot color becomes clear, but it might be a helpful check if you have any that are otherwise confusing.

This was the kind of answer I was looking for!!! Thanks!! I really appreciate all the detail. I’m trying to learn more about genetics.
