New Hatchout - For Fun, Any Guesses On This Chick?

I don't need to know, but for fun - what breed does this one look like (I have zero way of knowing, it's a BYM).

The only fertile roos at the time of conception were BOs and this mix of a guy who is half BO, half EE BYM. Two are dark so far. The other one is entirely dark including their beak and feet.
