New chickens, sexing help

[Jaymez]

So i got two new chicks and have started introducing them to the flock. The two new ones are the white one and the little dark one. I'm almost positive that the white one is a hen and my rooster must think so too because he tried to hop on her. I'm not sure about the little one though and i think I might have to wait a bit to find out, but any guesses would be appreciated.

Agreed. Please post good, clear photos of the combs, crests pushed back with one hand if possible. Have some one hold the birds for you to make it easier to get a photo.
They could very well be female, though that your rooster jumped on one could just be him showing dominance.
