Place frozen chicken in baking dish. Put it in the oven at 350 degrees. After 1 hour put a little more than half of the butter on the chicken, covering all over. After about 2 1/2 hours take the chicken out and put the rest of the butter on the chicken and baste with any drippings from the pan. Grind the lemon pepper or any seasoning you prefer and finish baking until the chicken reaches a temperature of 165 degrees.
