Hen or Roo?

[Blue Raptor]

Hey guys, this is my second hen or roo question. Last time (1 week ago) everybody said that she was a hen. She is a 2 1/2 months old Black Australorp. So far, she has no saddle or hackle feathers, and I think she is starting to get a little broody (even though very young) but I just want to make sure.
Here are 3 pictures of her: View attachment 2687497View attachment 2687498View attachment 2687499

Looks like a pulley to me.
