How about the possibility that the area of skin preserved on the fossil simply had no feathers, but the rest of the integument did? There are many living birds with bare patches of skin on various parts of their anatomy (and of course all but a few species have scales on their legs and feet). Just because part of the animal was covered by scales does not mean that the whole animal was.
