Sexing frizzle Brahma barnyard crosses 10 & 12ish weeks

[Sumer]

Hello I’m wondering if anyone can help sex these cuties. Moms are light brahma and dads a frizzle barnyard mix. I think they’re about 10 (buff) & 13 (black) weeks. Any guesses on gender and or what they might be mixed with? They both have black skin and crowns look black as well.
Thanks!!

I would guess there is some Silkie in the mix. Silkies have crests on the head, black skin, and black combs. Frizzle is often found in Cochin bantams, so the father might be something like a Cochin/Silkie mix.

For gender, the black combs make it hard, and I don't do well with frizzled feathers either.
But guessing from the size of combs, and considering they are 10 and 13 weeks old, I think you might have two females. I am more sure about the older one (black), because "she" has had more weeks to grow and still has such a small comb, but I am not completely certain of either one.
