Back yard mix Pullet or Roo

[Egrossman104]

Hello all, I posted the other day regarding my situation. I hatched out 22 chicks, and kept 5 thinking I would end up with 2-3 hens and I gave the rest away. Fast forward, they’re now over 7 1/2 weeks old. I have 3 confirmed cockerels and I’m thinking my other two could be as well. Here are some pic ( the best I could get) let me know your thoughts on breed and gender. The black one has an extra toe so I think that could be a silkie cross.

Brown one, I'm thinking pullet - not much in the way of comb or wattle development.
Black one, I'm thinking cockerel - with that much wattle in a 7.5 week, that's likely going to be a roo.
