Virtually the only reason geese need housing is for protection from Predators. Other than that, a windbreak is necessary in winter in cold northern climates. They have thick down and their feathers are waterproof. Their drinking water will freeze loans they will die of thirst before being much affected by cold. They should not be housed with chickens because the environment they create is unhealthy for chickens. Geese muck things up, chickens need dry space. A goose tractor would work excellent but necessary pace requirements vary base on length of time they spend in tractor.
