8 week buff Orpington, hen or roo?

[El Horno]

This is my 8 week old Buffy, we were told she is a girl when we got her at 2 weeks but a few days ago while I was letting them out i noticed she started crowing, not cawk a doodle do, more cawk cawk cawk, but definitely different than the other two she has grown up with. The hatchery we got her from with exchange her so it's not a big deal, but we have grown fond of her and hate to see her go if she ends up being a rooster.

100% rooster. This is what hens look like at that age
