Any special tricks on sexing Cochin chicks?

[Feather314]

Specifically, I’m getting a batch of 12 blue Cochin chicks in mid to late April and was wondering if there are any tricks I could use to sex them so that I can assign a proper name to each of them. As I said, I don’t have them yet so I can’t post any pictures, but any help would be much appreciated!

Generally boys will get pink combs by 5 weeks. They often feather out slower too, but not always.
