Pretty egg! Looks like an olive to me! What breed/mix hen laid it?

I just don't know. If I had to make an educated guess I'd say the only surviving chick from the summer. She is a cross between an Easter egger mom and golden wyandotte dad. She looks just like her mom. But it would only be a guess I truly have no clue who laid it.
