Oh, and just an FYI, geese are powerful creatures. An incident with the 'tame' American Buff gander after his babies hatched left me, a large adult, with blood blisters on my calves, thighs, and arms, bruises (from wings) on my legs and arms, and bitemarks on my legs and arms in which you could see every indentation in his bill a week after the incident.
I love geese, but I think people might underestimate them and have expectations of them that are unrealistic. Geese are smart, personable, and have very interesting group dynamics unlike those found in ducks or chickens, but they do require different handling and precautions during breeding season. They aren't cute and cuddly little wumpkins incapable of hurting a fly, they are protective of family, nest, babies, mates.
That said, there is nothing like going outside and calling for your geese and having seven large birds come running from across a field to you. They learn quickly, in the summer I would herd them from pasture to pasture and they learned the routine in no time, gathering into a group and following me. All this from geese that were not 'used to handling' or babied.
