Sex and breed 2 months old?

[DerekC]

Hello! It’s getting to the point in my backyard where I need to separate my hens and my roosters. Where I live, roosters aren’t allowed on any property so we have to get rid of them unfortunately
Anyways, can someone help me identify these specific chickens’ sex? (And their breed if you can )
-I would like to know the barred rock sex, the fat gray one, and the fat white one. Thanks for your time I hope these pictures are good enough.

All of your brown chickens are Isaac browns I have 3 Isaac brown the same age and I am having trouble sexing them

I thought my brown chickens were Rhode Island reds?

I'm seeing quite a few cockerels.... if you could get individual pictures, that would make it easier to identify them.

At 8 weeks old I think the white one is the only one that may be a pullet. The combs are quite developed on the other 2 for such a young age.
