A Brahma would not have a black face or legs. Even as a young chick, a Brahma would show yellow legs as well as a horn colored beak. I see a Silkie or Silkie mix in that chick. Not a Brahma.
ETA: There is also, as of this moment, no blue Brahmas that are recognized as a variety or have been seen in the U.S.
