Lots of pics, see what you think they are?

If they're 4 1/2 months old, that means they are close to laying age. The only definite cockerels I see are the barred rocks (the coloring says male). The black & the buff look like pullets - no pointed hackel or sickle feathers. I don't know much about light brahmas, but the comb on yours seems small - I would guess female.

They all look like hens to me, except for the Barred Rocks. Those are most likely roos.

I agree, the two BRs look like roos.

Our flocks look almost the same! I have one Australorp, one BO, two BRs, and one RIR-mix!

I thought for sure that my BO was a boy and I have no clue on any of the other ones. I thought they didn't lay till like 6 months? Are you all sure the BO and the Austro are pullets?
Thanks again!
