People with hard winters feed hay to the geese - can't remember if it is alfalfa, or orchard or what. Some geese will eat it, some not - but if there is snow everywhere, my guess is they'd eat it. My geese are always chewing on things, but our climate doesn't involve a lot of snow. They love lettuce too, melon rinds, and bread, but the bread isn't good for them in large quantities.
All geese are noisy -- no quiet breeds. You can't hear someone talk 2 ft away when they are all honking at once. Now, usually, they don't have such a big commotion, but they are awake all through the night at times, so it is completely possible to hear a goose conference at 3 a.m. . . . You'll have to decide if the neighbors will tolerate that or not . .. good to ask the question before getting the geese!
Our neighbors love watching the geese, and so far haven't complained about midnight goose noises . . .
