What breed of chicken of this?

[BantamLover21]

i don't think she is a Black copper Marans, because when i looked them up most of them didn't have bronze neck feathers like my hen.
I think she might be a black star.

She is not a Black Star, since she has feathered feet.

The "bronze" neck feathers are the reason a black copper Marans is called a black copper Marans. The copper refers to the red neck feathers in females. If they don't have the red, they're simply black Marans.

With my hen she only has copper coloured feathers on the front of her neck. With most of the black copper marans they have copper feathers all around the neck.
