What could this chick be?

[UnlabeledMama]

I got 5 barnyard mix chicks. I was told they were a mix of RIR, Buff Brahma and Dominique. Two are obviously mostly Buff Brahma and one looked more RIR and one has Dominique barring. But then I have this one. It is solid black with black legs and beak?

This is the best I have of her (?) face - lower right hand corner.



Also her ...



Any thoughts?

Likely a RIR over Dominique hen, which would give you a black sex link. And it would be a pullet as well based on coloring.

That completely makes sense!

Here is my black sex link pullet (welsummer rooster over BR hen)

That looks just like her! Thank you!
