When I was a kid, a neighboring farmer raised a group of 6 white turkeys. They did that same thing, terrorizing every car that drove onto the farm. They would hop up on the hood and peck at the windshield. He said that year he didn't have a single salesman come to the door. He raised turkeys for several years but never had another set like that. We ate one of those birds for thanksgiving...good stuff. I've butchered tame turkeys many times. A big tom is a quite a handful when he wants to be.
