I think slugs will do the trick.
Are you kidding? Have you ever TRIED to shoot a turkey?!?!? You have to use a .50 cal, and HOPE that the bullet doesn't bounce off of it's armored feathers.
or use a RPG, itl be a baked turkey, but at least itll be edible
Call in an airstrike.
Call chuck norris to kill it and theres your dinner.
He said it left, there's no use telling him to shoot it.
