I ordered mine from the local Runnings. American Buff. Three geese and a gander. $15 for the gander but the geese were $35 each. Try one of your local stores rather than having them shipped. They don't need a pond. We have one but they haven't found it yet. I'm getting an egg every other day from each of the girls now, but so far none fertile. I think our days are still too short for the gander. I've seen him climb on a couple times, but Holderread says they need a 12 hour day to be fertile. When it warms up some I'll put out their kiddie pool. Even a few inches of water helps the fertility, or so I'm reading. They're heavy birds, and they're considered a medium-sized breed.
My geese are among the few birds I would bring along were I to move (which we're seriously discussing because it's SO COLD.) Them and the Sweetgrass Turkeys. And my nice cows (I'm selling the mean-girl irregardless) and their handsome consort. And the doggies of course. None of my birds are pets, but American Buff are supposed to be the most family friendly, and I read on here of people whose geese ARE pets and very affectionate (except maybe during breeding season).
