So when I first got Graffy about a year and a half ago the only wing feathers he had were his coverts. There were no primaries and no secondaries on either wing. The four primaries you see in the pic grew in within the last two months or so, and they're the only ones that have grown in so far. Both of his wings look like this. He has maybe ten primaries total and still no secondaries. (He only recently learned how to fly. He's not very good at it yet).
Is this a genetic mutation/defect or is it possible the breeder plucked out all his flight feathers prior to selling him to the pet shop? (I know the pet shop didn't do this because the guys in charge of the birds there don't clip the wings unless the person buying a bird requests it).

Any thoughts?
