Geese are part of the duck family but are much bigger than ducks and, unlike ducks, they feed entirely on grass and other herbage and spend very little time in water. When they do swim, they do not dive.
A goose can live in excess of 20 years, so if looked after and managed properly, it is an easy domestic animal to keep and can be a cheap and productive asset. They have a reputation for being very good askaris, and some farmers keep them penned with livestock at night as they make a lot of noise if they are disturbed and can be intimidating if they attack as a flock.
