If you are cooking it in a roasting pan please figure 4 lbs per hour unstuffed.
If you are cooking it stuffed figure 3 lbs per hour.
Deep frying it is best to use some cotton string and tie the wings and legs in snug to prevent overcooking. It will finish generally 10 min sooner than the deep fry directions state.
If you are using any other method just figure they cook a little faster than store bought commercial brands so check on it and watch for the timer to pop up usually 30 to 15 min earlier than the directions they give you.
