Not feral. They have all the qualities of the domestic variety.

I ran into a flock of seven unbanded Swan Geese near Astoria many years back and all had a characteristic large knob at the base of the upper mandible. These knobs are sure indicators that the birds are from domesticated stocks as the wild birds in Asia almost always lack them. If there are no knobs then they're most likely from a private bird collection. The wild birds also have less white in the face and neck~ still pretty neat to find them out here!
