Raise them like dogs, meaning spend the same amount of time with them as you would your dog and they’ll adore you! Also you can pair males together or females together or males + females together without to many issues, ganders can be argumentative with each other in the breeding season but not always, I have a few sets of ganders that get along just fine.
Geese are waterfowl but the great thing is that they aren’t as messy as ducks, at least my geese aren’t as messy as my ducks, I have 4 ducks who currently go through as much bedding daily as my 11 geese. That might not be true for everyone I suppose.
Ganders can be very parental, they’ll adopt goslings that aren’t theirs and even ducklings!
Geese seem a little less instinctual than ducks, they’re a little smarter and can learn more words, they like routines, are very individualistic, and can even be picky eaters so it’s good to introduce a wide range of foods when they’re young, though even still you’ll get some who just don’t like certain things.
