I was brought up with the theory that the stuffing kept it moist.
Maybe get one of the appropriate size for your family and not too big, the bigger the longer you have to cook. Just pretend it is a chicken and double the size and cook the same way. Spoon some of the pan juices over the top of the chicken to keep it moist.
I always read the instructions for how long to cook and the correct temperature, so follow that as a guide.
