All Runners were originally bred in Southeast Asia for high egg production and excellent mobility. There is evidence of their ancient ancestry from stone carvings in Java that are over 2000 years old. These ducks are still being used as they were then. Flocks of ducks are herded daily from field to field eating waste rice, weed seeds, insects, slugs and other bugs. They are then put in a bamboo pen at night where they lay their eggs and are released the following morning to clean other fields. During the course of their lives the ducks may cover hundreds of miles in their travels. Therefore, a hardy mobile duck is absolutely necessary - you will not find a better foraging duck than the Runner.
