The Vergenoegd (VER-GIN-NEGGED) Wine Estate in South Africa houses over 900 Indian runner ducks and they go to work! When visiting, you would see them all parading through the vineyard twice a day, heading to work. They keep snails and pests away, reducing the dependency on pesticides. They've got one task and they do it to perfection! They end their day with a rejuvenating dip in the dam.
