The breed is mixed but what is the gender?

I see definitely pointy feathers around that 3rd one's neck and he looks more manly around the head. The 4th, both girls as well as the ones in the last pic. The first two I could go either way.

I think pics 1 & 3 are roos and the rest are pullets....but that might just be me.....and chickens can and will surprise you.

Eventually, they will either lay or crow. You'll know for sure at that point...
