Identifying gender and breed?

[tn_artist]

I have a beautiful Blue Laced Red Wyandotte named Adam.
I've raised chickens for a while but this is my first Wyandotte. I don't know if Adam is a hen or roo! Any assistance would be helpful. He or she is just shy of 3 months old.

I also have a beautiful little lady named Ira that I like to call my 'mystery chicken'. She came in a mixed batch- but she doesn't match up with any of the breeds I ordered.
The closest breed I can find is a Cochin, but Ira has FIVE toes on both feet, with leg/foot feathers. When I first got her, I thought I'd accidentally ended up with a Silkie. She's definitely not a silkie...
She's a couple weeks younger than Adam.

She looks just like my Ebony, other than color of course.

Thank you for the help! I thought Adam might be a roo judging by size and the early comb but he's so docile and sweet (and round!) that I was uncertain.
I ordered pullets and ended up with at least three roosters. Hopefully I can keep them without any trouble.

Wyandottes are a duel-purpose breed (meat and eggs), so it's most likely normal Adam looks round. It just shows he's packing on the mass to become a future meaty bird, as per the standard of his race ^^

Good luck!
