What Gender is This

[Jmelee09]

I have a barred rock chicken that is exactly 10 weeks old. I've gone back and forth on if I think it is a rooster or not. It is about the same size as all the others (black sex link chickens), the comb is also about the same size although redder than there's, as there are black, and the tail feather look similar. My chance for it to go to a farm if it is a rooster is next weekend, but I really want to keep it if it is a hen. How do I tell?

Looks like a heritage pullet.
