Over the ensuing millennia Native Americans domesticated comparatively few indigenous animals, in contrast to the many animals that were genetically and behaviorally modified from their wild ancestors through captive controlled breeding in the Old World. New World animal domesticates included only two large birds (the turkey in North America and muscovy duck, Cairina moschata, from Mexico south into South America), a medium-sized rodent (guinea pig, Cavia porcellus), and two camelids (llama, Lama glama, and alpaca, Vicugna pacos).” Link

To take advantage of all this experience and ensure the genetic quality of our products, (French consultants continue to visit our operations every year). The birds are barn-raised without the use of steroids, antibiotics or growth hormones. We don't hurry nature: we grow our ducks for 70-85 days compared to 42-45 days for most Pekin ducks. This allows the bird to fully mature. Feed is carefully selected for a balanced diet and for the best possible yield and flavor." Link
