How long to cook an 8 pound duck in the rotisserie so it's really juicy?

Well, darling, if you want that duck to be juicy and delicious, you'll want to cook it in the rotisserie for about 2.5 to 3 hours at 350°F. Just make sure to check the internal temperature with a meat thermometer - you're aiming for 165°F in the thickest part of the bird. Trust me, follow these steps and you'll have a quacking good meal on your hands.
