pullets or roos?

[EmilyEnns]

hi there! looking for some help sexing my chicks! they vary in age but i believe the youngest are 10 weeks now and the oldest going on 15 weeks. It might just be me but i think they are all roos i have 18 chicks and i’m only sure of 6 of them being pullets because they obviously don’t have any cockerel traits! again would love some help!

1,2,5,6,8 all appear to be cockerels.

I see 10-11 possibles in pic 3. 6 in pic 4. 3 in pic 7. Pretty much most with bright red combs at this age. Also those with dark red patches over the wings, and pointed saddle feathers should grow soon.
