Brahma, Americana, or Olive Egger?

[Potato and Eilonwy]

Hi! Its been a while since I was online here, and I just went to tractor supply and bought 4 new chicks for my flock. We got 2 Olive Eggers, one with feathered feet, the other without. Then we got 1 Buff Orpington and 1 Americauna. Everybody except for the Buff Orpington were straight run, and the Olive Eggers and Americaunas were in a bin with Brahmas as well. We were wondering if anybody could tell me what gender these little dudes are, or what breed?
All 3 of these chicks were from a straight run bin with Olive Eggers, Americaunas, and Brahmas.
Were hoping this is an Olive Egger.

This one were hoping is an O.Egger as well.

And this last one were hoping is an Americauna.

And we already know the Buff Orpington is a girl.
What do you guys think? Are these Brahmas or Olive Eggers? Boys or Girls? Let me know please

Yes the first two are olive eggers and the last one is an Americana, (I had one before and he/she was fluffy like that too). And for the genders, it is too early to tell.
