From Gozzi's Turkey Farm in Guilford, Connecticut, these turkeys are Gozzi Whites. Their feathers are known for being white and their meat is renowned throughout the region, to whom the Gozzis supply over 18,000 turkeys per year. Non-toxic, vegetable-based food dye is applied to their "blank canvases" to create these bright colors: it's all topical and harmless.
See a video of the turkeys at Fine Cooking. Have you ever been to visit the famous Gozzi turkeys?
