Copper Marans, 6 weeks. Hen or roo?

Bought these 2 chicks as unsexed. The one without the vibrant is comb is way larger. I am thinking the smaller one may be a roo. Thoughts?

The one drinking is the much larger chicken I am thinking pullet. The other two pics is the same chicken that I am thinking is Male.

I think the one with the larger, red comb is a cockerel.

I think you might have a roo on your hands....

I'm guessing that bigger comb is your cockerel.
