The chickens are invading your property. Their intentions are yet to be known. It's better to be safe than sorry, so shoot them down.

* A variety of chickens that will try anything to land on your property
* Big chicken bosses, don't let them lay eggs.
* Several different weapons at your disposal.
* Collect roasted legs to buy new weapons.
* Bonus legs for headshots. (I mean, sometimes, a chicken drops more than two legs)
