I'd say if neither one has muffs (cheek area) or beards (under bottom of beak), then you have BB's, not d'Uccles. The d'Uccles do have the muffs and beards, but the Booted Bantams do not. I have both the BB's and d'Uccles, I personally like the muffs and beards, that's just me. I still keep my BB girls though because they're so sweet and pretty. PM me if you have any questions.
