Indian Runners (Anas platyrhynchos domesticus) are an unusual breed of domestic duck. They stand erect like penguins and, rather than waddling, they run. Their legs are positioned at the backs of their bodies, so they are literally able to run. Indian runner ducks are prolific layers and active birds who love foraging. They rid the ground of pests, making Indian runners a breed of some use to humankind. Indian runner ducks appear to have been around for a long time. Carvings on stones in an ancient Javan temple suggest runner-type ducks may have existed around 2,000 years ago in Indochina.
