Packaged bread stuffing seems very dry adding broth anything else I can do? Also inside or outside the bird?

Cover the pan with foil for the first half hour or so (i.e., remove the foil just long enough to make the top brown and crunchy). Also, it would help a lot to add some fresh veggies, like onions, celery, maybe even some fruit like apples or pears, and fresh herbs like parsley. They'll release a lot of flavorful juices which will also moisten it. And if you put it inside the bird, it definitely will be much more moist than if you cook it separately. Have fun!! ;o)
