Is this a Rooster?

It was supposed to be an ameraucana hen but at 15 weeks I have my suspicions even though I have heard no crowing.

defiantly a rooster!

 

[Fowlfellow]

He will be crowing soon!

Yeah...that's a cockerel.

This is Dela. She(?)is just over 14 weeks old. She is larger than the other chicks the same age and is more aggressive and dominant. Compared to the ameraucana roo above she looks very pullet, but since she is larger than the others and has more wattles it makes me wonder. What do you think?
