His home-made inventions rely on creative problem-solving and hi-tech materials to gain the most wholesome use of his land and livestock. Featured in Food, Inc. and Omnivore's Dilemma, Salatin sums it up with his latest book title--Folks, This Ain't Normal: A Farmer's Advice for Happier Hens, Healthier People, and a Better World.
