A Vietnamese farmer claims he controls thousands of ducks using only his voice.

A video showed thousand of his birds waddling along obediently as he let out a variety of whooping noises.

The farmer said it took his 6,000 ducks a month to learn his calls.

The clip was filmed in Don Nai on June 16.

The video captured the moment of the man used his voice to control thousands of ducks out of the stable in the farm in Dong Nai, Viet Nam.
According to the filmer, he is a duck breeder. He has a duck farm with about 6000 ducks. These ducks are raised and trained by him.
Every morning to call the ducks out of the barn he emitted the "Cúc" "Cúc" call. The ducks when he heard his call immediately got out of the stable and followed him. These ducks only listen to his call.
It took nearly a month to train the ducks to follow the man's command.
The ducks after leaving the stable will follow the man to the river bank and return to the stable in the afternoon.
