Look at the package to tell you how long to cook it. I like to rub mine in vegetable or olive oil, salt, pepper, and garlic. Then I put foil loosely over the top, cook it for like 2 hours, then take the foil off and keep cooking for the last 2-3 hours.
Wet turkey fabric and a good sturdy needle lol Dh always deep fries his. The night before he injects the bird with seasonings and lets it marinate over night. It only takes 3 mins per lb of bird so it cooks fast.
