Oh, also whatever you get make sure you handle them a lot. My geese tolerate my husband who's never had much to do with them. They follow me everywhere and make a fuss if I'm in the garden and they can't in, the same as they do when they are separated from each other. They are fine with the children who handled them a lot as well, but the kids aren't always calm and quiet around them so they tend to stay out of the children's way. Which is fine so long as they don't get aggressive.
They free range during the day right now, but may have a pen next year. Depends on whether we have the money for all our fencing projects!
Oh, and they're fun to herd. I have to chase the ducks a bit, waving my hands and stick around to direct them where I want them to go. To move the geese, I only have to peep and walk. They just tag along behind unless I'm trying to put them in the hen house before sundown. They're not dumb, after all.
