Sexing Month old Cochins

[Sachasmom]

I have a bunch of month old Bantam Cochins, Can you tell on the sex on these guys yet?
What should I be looking for?
I'm hoping for better luck than sexing Ameraucanas, two of the ones I saved out last year ended up both being Roos!

I had a cochin rooster who showed pretty early that he was all boy. His comb was bigger and redder than the girls at a few weeks old. At around 3 months his tail began to curve into that familiar rooster shaped tail. Got any pics?
