There are some animals that roam the map now and one of those is a chicken. They are good for killing for their animal bones and meat but for this quest we need to keep it alive.

Approach the chicken and you will see a notification to press a button to pick it up. When you have it in your hands and jump you will hover slightly allowing you to jump further. Who remembers Zelda: Ocarina of time?

The best way to guarantee you fly for at least 20 meters is to jump off a hill.
