Sourced from specially bred ducks that are raised to forage on land rather than water, raised with room to roam, socialize, run around, preen their feathers and be just about as ducky as any duck could wish. It should be noted that almost ALL ducks raised in the U.S. are cage free and are by law hormone and antibiotic free. What separates this cage free duck fat from the competitors is the small batch, kettle rendering and advanced fine-filtering creating the purest, BEST TASTING cage free duck fat on the market!
