What gender are these

[rigochickens]

I have 10 naked neck chickens I picked up today and I wondered what gender they where. The 10th one was being difficult.

How old are they? There appears to be three roosters in the mix, if they are under 12 weeks of age that is.

They are nice looking birds!

All the white ones and the red one in front look like cockerels, but it's hard to see all of them in the picture

The ones with the red combs already are likely cockerels - but the rest of the pics are hard to see.
