Turducken is a dish consisting of a deboned chicken stuffed into a deboned duck, which is in turn stuffed into a deboned turkey. The word. turducken is a portmanteau of turkey, duck, and chicken. The dish is a form of engastration, which is a recipe method in which one animal is stuffed inside the gastric passage of another.
The thoracic cavity of the chicken/game hen and the rest of the gaps are stuffed, sometimes with a highly seasoned breadcrumb mixture or sausage meat, although some versions have a different stuffing for each bird.
