Brahma cross hen or roo

[Sumer]

Hi, I posted these two yesterday with no replies. I’m hoping that maybe some better pics will help. These are supposedly Brahma cross (Brahma and barnyard mix). I would love some opinions on if they’re hens or Roos. They are around 10 & 12 weeks, give or take. Thank you!

I'm not very good at telling gender of breeds with black combs. They're also frizzled so that makes it harder. I think they're both hens but I could very well be wrong.
