No need to be sorry at all-- just trying to make it clear for new folks. And yes, you can be pretty certain it's a girl. A cockerel would have blue feathers coming in at the breast, since they eventually have a completely different color pattern from females in this variety.
Blue wheaten is a color type, not a breed. I think the breed in this case is Ameraucana, so it's a blue wheaten Ameraucana pullet. I agree it is pretty!
