2 Wyandotte's 2 different combs? Hen or roo?

[ryansmom06]

Hi i have these 2 6 week old's. They appear to have 2 different types of combs. I fairly new to this so my question is does this have something to do with sex of the bird? The first 3 are 1 bird and the next 3 are the 2nd.

One has a single comb, faulty genetics, common in hatchery birds, where they breed for quantity, not quality. The other has a rose. Looks kinda like a roo...

Wrong comb type is common with hatchery Wyandottes. One has a rose comb "correct for the breed" and one has a single comb "incorrect for the breed". If they are just 6 weeks old I'd say they are both cockerels.
