Need help determining gender and breed of these 4 week old chicks

[crownsparkles]

Hi! I'm new to BYC and last month my Cochin hatched 4 fertilized eggs. I bought the fertilized eggs locally hoping to add some new egg colors to my egg basket;-). She gave me one green egg, 2 brown eggs and 1 white egg. We are unable to keep roosters here in our area so I need help determining gender on these guys!!
I'm pretty certain the white one with the already red comb is a roo but not sure at all about the black one??
Thanks in advance

At 4 weeks that's an awful lot of pink and comb growth - third picture down, bird on left is the only one not sending out some roo flags to me - but I'd wait a couple of weeks and re-post.

Thanks so much! That just what I suspected. But was hoping for another girl.
Any idea what breed the white chicks are? They have some black spots here and there?
