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.
As they are light in weight, there is also less chance of them trampling the vegetation in your garden or yard.
Because of the high egg production of the native ducks, there are many duck eggs used in Southeast Asia. Not only do they replace the typical chicken egg but duck
eggs are made into two unique products, the balut (a partially incubated duck egg) and the salted egg (fresh eggs put in a salt solution or salt mud until the salt
has permeated the entire egg). Due to the emphasis in coloration over the past 80 years in the breeding programs in England and the United States, the Runners no longer excel at egg production. They are very average at this point.
