Can someone tell me what breed this girl is?

I’m so confused on what breed this girl is, the other pullet that I got at the same time as her has a red comb but this one’s comb as slowly turned black as she gets older. I really just want to know what possible breed she could be because i really like the way she looks and want more chickens like her lol. She’s around 14 weeks old in these pictures.

Black Cooper Marans maybe. Wait for the eggs. If she lays darker brown Marans she is.
