Please take Freddie to an Avian vet. It sounds like infection is already setting in with how you described his breathing and you don't want to cause more trauma to his wings by pulling at the feathers. If you cannot locate an avian vet call the pet store or breeder where you got him and ask where they get their birds treated.
I hope Freddie finds the help he needs asap.
