Need help to Identify RIR at 10 weeks old

[chick_magnet]

I have to camera and i am try to see how many pullets i have in my backyard flock. I have no camera to post pictures so i was hoping maybe some with a camera can post some of there RIR chicks. I have heard i'm suppose to look at the tail,comb,and wattles. The more I try to id the pullet or the cockerel the more i get confuse. Do anyone have pictures of their RIR on here?

You should be able to tell a difference now. They boys will have much larger combs, and their feather will be more wiry, where the girls will have sleeker feathers.

A boy at about 6 weeks

A pullet- she's probably 10 or 12 weeks here.
