Greylag Geese typically lay 5-7 eggs, incubated by the female for four weeks. From the moment they hatch, their downy young can walk, swim and feed themselves but it is seven to nine weeks before they can fly. When thrown, this egg has a 12.5% chance to spawn a completely passive gosling that will never attack players in any way, only running around in a panicked manner upon taking damage; after 1 day, the gosling will grow into a white goose. However, they have a 0.782% chance to lay a single Golden Goose Egg in place of a regular Goose Egg.
