Hi all! So glad to be a part of Backyard Chickens. This is my first post. Of my four baby chicks (who are now almost 2 weeks old), 2 are supposed to be Buff Brahmas. The feathered feet of both of the girls gives me reason to believe that they are in fact both Brahmas, but one has a much darker head and back. Does anyone have any insights into this? Is she a Dark Brahma, an irregularity, or something else? Thanks for your thoughts!
