Ducks are small and require less space to raise.
However, ducks require a grain supplement year round and are more prone to predators. Geese require twice as much space. However, geese do well on limited grain when they have plenty of area to graze and are seldom bothered by predators. If you wish to raise waterfowl for meat, they can be purchased from a commercial hatchery or local feed store. Emden, African and Pilgrim geese are the most common breeds of geese raised for meat.
