What about ducks?

Probably only as farm livestock on large rural lots, but not spelled out. Robbinsville's rules cover 'fowl or other farm livestock' without defining fowl or mentioning ducks, so confirm with the township.

§§ 142-13, 142-16, 142-33D, 142-108: "If ponies, horses, cows, sheep, fowl or other farm livestock are kept on any property" Duck coops we build.
