please look into the way these cheap turkeys are made. The reason the label says "young" turkey is because they are given so many hormones to make the breasts large (since that's the part everyone wants) that if they are allowed to reach maturity, their legs could not support the huge breasts.
Read Animal, Vegetable, Miracle by Barbara Kingsolver. And try to find a local farmer to support by buying a fresh, hormone free turkey!
