A turducken is a partially boned turkey layered with a boned duck, then with a boned chicken and spread with layers of stuffing between each bird. The entire mass is rolled, tied and roasted at 190°F for 12 to 13 hours. According to the USDA Meat and Poultry hotline, this recipe has been circulating for a number of years.
Make It Safe: USDA Hotline representatives recommend keeping the birds chilled until ready to assemble. While boning each bird, keep the others refrigerated. After all three birds have been boned and the stuffing has been prepared, assemble the Turducken ingredients and quickly get it into a pre-heated 325°F oven. Use a meat thermometer inserted in the thickest part of the bundle and cook the turducken to an internal temperature of 180°F or more. Check the temperature in several locations.
