Cotton patch geese are an sex-linked, American heirloom breed that were bred for weeding, meat and eggs. Medium size they are friendly, relatively quiet (although they do like to gossip with you when you greet them for the day), and nice (mine have never attacked me or visitors-- unless I'm stealing eggs). Males are white, and females are grey or grey patched. They all have pink bills and legs.
Once common on Southern farms to weed cotton fields, the use of herbicides put them out of a job and in danger of extinction. Considered "threatened" by the Livestock Conservancy, this could be your opportunity to help save a historic breed.
$50/gosling . sex-linked so breeding pairs possible (three lines of unrelated genetics have nests).
