Help with breeds and sex of 3 month old birds

[Prairie Woman]

Any help would be appreciated. I got these from a teacher friend who hatched them in her classroom. I'm thinking I have all roosters except the smaller black/white one? Crowing is the only way I know how to tell for sure. Butchering soon so I want to be sure! I was hoping for more hens but I'll make due with whatever eggs I end up getting. I know I have 3 hens in my second younger flock (not pictured). Once the roos are in my freezer I'll combine the two flocks. I have no idea on breeds. All new to me. Thanks!!!

The next 3 birds in question have yet to crow in my presence.
The multicolored is a dominant rooster. Not sure on the black one - has bluish tint to feathers, fat neck, medium size comb.


Is this a roo? Dark bird with some red.


This is my most affectionate bird. But he is probably a roo so I'll eat him too.


The first cream colored one is mean so I'm eating him/her either way. Red previously pictured. The small one is a girl I think? I'm told she may lay neat colored eggs? Not sure how she is surviving in a world full of men


One more question, should I pen up the roos and feed them something other than chick starter for a while before we butcher?

Any and all help is appreciated! I'm a former city girl turned rancher's wife and I have a lot to learn! But I'm loving every minute!

I see one pullet/hen. She looks like an Easter egger so yes, could have colorful eggs. She is the white and black one in that last photo.

Your luck sounds like mine!

A better pic of the black and white bird would help be certain of gender. I'm not seeing much comb or other male signs, but that is often a male coloring. The rest are all definite roosters.

I don't pen my butcher cockerels separate or feed them different, but some folks do finish them on corn to get nice pads of yellow fat above the tail. That fat makes great pie crust for savory pies

Thank you for the help! I'll get a better pic of the black since he/she seems to be my last hope. That chicken is very shy.

At least we will eat well!
