Hen or Roo? Plus breed identification

[alliculley1]

Hi there,
This is Mabel, she was sold as a female but I’m paranoid that she might be a rooster. She is very sweet and friendly. I got her from my in laws after offering to nurse her back from her splay legs. I’m not sure what breed, my guess is a blue Australorp. What do you all think? I think she is around 7 weeks.

I'm sorry, can't offer any insight as to breed or gender. All I know for sure is that it's simply precious.
My semi-logical brain is saying 'At least that comb isn't red....'
