What breed are my chickens?

[RoostersAreAwesome]

The red hen is sex link cross of RIR roo over Silver laced wyandotte hen. Not a common sex link mix but TSC ocasionally has them. I forget the exact name, but it might be something like Brown star or Brown sex link.

The white hens are not Cali whites or Austra whites. Both are dominant white over black, and always produce white birds with black specks. No red anywhere in the genetics. They could be Amberlinks or some new hybrid mix.

I agree that the first hen is a red sex link. Also known as bovan browns or isa browns. This is a thread that mentions RSL crosses involving wyandottes: https://www.backyardchickens.com/threads/cinnamon-queen-thread.938674/#post-14380819.
The other two both have red leakage, so they aren’t austra whites. I’ve seen a few similar hens on here, but I couldn’t find the breed. They’re very likely leghorn hybrids.

And as I mentioned the tractor supply chickens are like that. Meaning the comb is not right by your standards but fine by theirs

The comb is right. The hen is just a different kind of red sex link.

The white ones with the black spots look like my neighbor's california white chickens...they have that rusty coloring on their chest also, which she that was staining from their feed and water, but maybe it's actually their feathering.
