Is my frizzle a boy?
That's a pretty pink comb and a good set of wattles- I'm leaning rooster. How old is the bird, though?
I'd say it's pretty certainly a boy, then. Hens don't typically get that pink/red until they are about to lay, and he's too young.
He's a cute little thing- I've always had a soft spot for frizzle cochins.
