Hunting wildlife includes the following animals. Chickens, boars, wolves and frogs. If you see one, kill it.

You should be able to hear any wildlife that is nearby or see it if you have visual sound effects turned on.

It's not easy to pin point wildlife as they roam across the map but there are some places I would recommend checking out.

Stealthy Stronghold. There is usually some wildlife inside the walls of Stealthy Stronghold. There is also a good amount of weapons so you can drop straight in from the battle bus.

Colossal Crops. There is a fenced area outside Colossal Crops that always has 3 boars inside.

Woodland areas such as Weeping Woods is also a good place to search for wildlife.
