In the video, we see a black duck with a white patch on its neck standing in a pen. The duck is standing next to a pile of hay and a white plastic bag. A person's hand is holding a metal tray filled with grain, and the duck is pecking at the grain. The person then moves the tray away from the duck, and the duck follows the tray with its head. The person then moves the tray back towards the duck, and the duck pecks at the grain again. The person continues to move the tray back and forth, and the duck follows the tray with its head each time. The video ends with the duck still following the tray with its head.
