Which of these are roosters???

You can put near them your smartphone and ring to it, those who run directly to it, must be hens....

The front ones look like boys, and as well as I can see of the back, they look predominantly female. It looks like there are two black ones in the back ducked down out of the picture. But in the back, the far back is a female and the far right is, and perhaps the one in front of her.
What will you do with the boys?

I agree, more pictures will help.. from that current picture it seems possibly majority roosters. The orange and the furthest back one with no red on comb at all are the only ones I was sure are females.

The two black/white in front plus the black one are all clearly roos. B/w on right seems to be roo behind in development plus possibly having different comb type? Another b/w one is a boy behind in development compared to the front roos.

Things to look for- pick up a roo and ruffle up the feathers on back and neck- roosters have long, super shiny and much longer, thinner feathers with pointed tips. On females the same feathers are shorter, either not shiny or with less shine with much more rounded tips. Pick up the orange hen and the black rooster first to compare the difference in feather shape.

The boys also already have the curvy rooster type feathers- the ones that get a little long and curve over the "real" tail feathers which are bigger broader and stiffer.
