I'd disagree... this is my dark brahma chick, 4-5 weeks in this pic. It could be brahma... but I would guess a mix with those colors... Does it have a single comb? or a pea comb? View attachment 1018397
@Frazzemrat1 Dark Brahma pullets and cockerels have different feather patterns. Yours is the pattern of a pullet while theirs looks like a cockerel. But since TSC isn't always reliable for pure breeds there is a chance of it being a mix breed.
