any guess on sex

[Bisqit&Gravy]

My 2 bantam chicks are 4wks old. The hen is a black japanese bantam and the rooster is a quail antwerp belgian bantam. The black chick acts alot like momma as for being freindly. Looks like her too and hold it's tail upright when walking around or perched.

I've been looking at their combs and the black one looks smaller. The combs on both of them are flesh color. I'm hoping the black one is a hen but not counting on it.

Here's a few pics....can't really see that much

I would say the black one is a rooster and the other is a hen. It is hard to tell with those pics. But that is my guess.
