With that comb, she's definitely a mix, she's not going to be some rare, exotic breed. The crest and clean legs lends itself to one parent having Polish, and the other parent having blue genes. The white lobes also say both parents were probably white egg layers, so Polish/Andalusian is as good a guess as any.
Crest is the feathers growing on top of the head.
Tufts are long feathers growing from the sides of the face.
Muffs are feathers growing around the face, shorter than tufts.
Beards are feathers growing under the face.
