Prepare chicken by patting dry the inside and outside to remove excess liquid. Mix the apple butter, Knuckle Dragger, and BBQ sauce together in a small bowl. Stretch the breast and back skin, then apply some of the apple butter bbq sauce under the skin. Feel free to additionally rub the whole exterior of the body with Knuckle Dragger and use any remaining apple butter bbq sauce.
Pour half of the apple juice into another container and save. Holding the chicken with legs pointed down, slide chicken down over the can so it fills the body cavity. Place chicken on grill or rack directly over the drip pan.

This should be approximately 45 - 60 minutes depending on oven type, however ensure that your internal temperature is 165°. Remove chicken from oven; cover and let stand for 10 minutes.
