Help with breed and sex! Mislabeled buff

[mountainmenagerie]

Looked like and was labeled a female buff at 2 weeks old. Now she’s 7.5 weeks. Not a buff. New Hampshire? Cockerel or pullet? I know the reds can have bigger combs even on females. I wanted a buff, oh well, but We can’t have Roos.

That's definitely a cockerel. Not sure on breed.
