6 week old BO gender

[hungry hunter]

I have 2 Buff Orpington chicks that are about 6 weeks old and I'm curious about their gender.

The one in front has a redder comb and waddles than the other, but it also feathered out first and seems to be ahead developmentally. Is it too early to determine gender?
Here is a little closer picture of them. I apologize for the poor quality, but they don't stay still for long...

Here they are on the roost.

The one does look to be a rooster by comb color.
