Returning with (hopefully) better pics of my chicken; hen or roo?

Back with better pics of this one Buff Orp we have, the size of it compared to the other Buffs and its curly tail feathers are mostly what’s making me think it may be a roo. I haven’t kept this breed yet so I’m not familiar enough to know for sure myself, and I appreciate any help yall can give me! Thanks in advance!
