They all look to be boys, maybe I see one pullet in there. Not sure about breed. Could be some sort of mutts.

I think the black one with the smaller comb (middle row, right side) might be a female, might be a different breed, maybe both female and different breed. The others look like males to me.

How many are we talking ... the 1st pic on the left is a cockerel as is the black on the right.
The bottom left looks to be a pullet, as does the black one on the right under the first black cockerel. The last one on the right is a cockerel
