Hundreds of ducks rush for food as they hear music in Vietnamese farm

Crazy footage filmed in Thanh Hóa, Vietnam, shows a farm owner using music as a tool to call for his ducks that need to be fed. The man uses a stick to make a sound that resembles the drums' one to draw hundreds of birds from the fields to the farm building. Long lines of quacking ducks rush to the scene as they hear the music. The farm has approximately 800 ducks. The footage was filmed on June 15.
