pullet, IMO. CM Roos are generally much lighter than females. What were you hoping for?

A pullet. The one with much more white on it as a chick went home with my brother. I hadn't seen that chick in three weeks. When I saw it last weekend, I noticed that it is darker than the one I have. I thought mine was fairly dark, but his is even darker.

Is it possible to sex CM as chicks like you can with BR?

I also thought the comb on mine was fairly light-colored. It didn't strike me as overly large or red. Also, the body shape looks more pullet to me. I need to take updated pics. The chicks are 12 weeks old now, so they should look more like roo/pullet.

Anyone else want to wager a guess on this one?
