Goose

Anser anser domesticus

In livestock and small-farm use, goose usually means a domestic goose, most often listed as Anser anser domesticus and descended largely from the greylag goose. Some breeds, including Chinese and many African lines, trace to the swan goose instead. Geese are large grazing waterfowl with long necks, sturdy webbed feet, strong flock instincts, and loud voices. Heritage and production breeds such as Embden, Toulouse, Pilgrim, Sebastopol, and Chinese are kept for meat, eggs, down, exhibition, weed control, and as noisy watchbirds around yards or pastures.

Keeping geese is closer to managing grazing livestock than keeping cage birds. They need room to forage, clean drinking water deep enough to rinse the nostrils, and a dry shelter that can be closed against night predators. A pond is useful but not required if water tubs are cleaned often. Breeding is seasonal in many climates, with ground nests and ganders that may become protective in spring. Buyers should match breed size and temperament to the property, check local noise rules, and plan for strong fencing and a long-lived flock.
