What breed of chicken is this?

[wkshaddon]

I bought her from Wilco I was told that she was a Jersey Giant but I am having serious doubts about that. Any idea of what she could be?

She looks like a nice EE to me?

Black sex-link or black star are possible

 

[Mother of Chaos]

Is she laying yet? If so, what color eggs?

I can’t really tell from the lighting in your pic: what color are her legs? -yellow, white, slate-blue, willow-green

She has a single comb, which is confusing me a bit.
