Ok, first of all roos are not bad. I have 64 birds and 4 are roos and I have another 10 for sure cockerels and I'm guessing at least 6 turkens SR are gonna be boys too.
I'll keep my best roos for breeding the rest go to Kamp Kold.
As for your guys, it's stilla bit young, but if I was betting, I'd say the BL polish is a boy and the GL, depending on the photo looked like a pullet. The first photo I was gonna say boy, but the second photo was a better angle and maybe girl. Remember - mohawk= boy, afro=girl.
The RIR look identical to my 4 girls as chicks. My RIR roo looked totally different as a chick. Just my opinion here...
As for the Brahamas, I have no idea, give them some more grow time. Boys legs will thicken and their combs will grow larger and redden. They will usually also get a more upright tail feathers than the girls. These things start to show fairly early, but yours aren't even fully feathered yet.
As long as you don't mind the crowing at all hours of the day, roos are not bad at all. I love my very pretty boys!
