Turducken is a de-boned turkey stuffed with a de-boned duck, which itself is stuffed with a small de-boned chicken. The name is a portmanteau of those ingredients, turkey, duck, and chicken. The cavity of the chicken and the rest of the gaps are filled with, at the very least, a highly seasoned breadcrumb mixture or sausage meat, although some versions have a different stuffing for each bird.
