Im going to guess a black copper marans

I saw a picture of a hen that looked just like her but no one could tell me the breed

Black sex link is a good guess- majority of them look more or less like her.

But could just as well could be a straight up mix. That kind of color and pattern is very common result of mixing, especially when black birds are involved.
