Please help identify breed

Hello! I'm new to these forums but have been reading to aid my learning for weeks! This chick is almost 3 weeks old. It was supposed to be a Plymouth Barred Rock but is completely black, even the legs and feet. Also, any ideas on pullet vs. roo? Longer tail feathers than the others and a little more dominant.

Thanks in advance!

It could be a black plymouth rock! though those are some tail feathers... and a pretty large comb. Though the comb is still yellow so arguable female!

Black sex-link maybe? If it is, it's a pullet.
