Hi KMBasingstoke
It’s possible, at this time of year that you might have 16 hogs visiting if some of them are this year’s hoglets. But a possibility is that a hog rescue may have released a group of hogs in your area. They should really be returned to where they came from or as near to that as possible – except in exceptional circumstances, but is has been heard of before that groups of hogs have been released in certain places.
Have you spoken to anyone else in your area about them. Because if some of the hogs are only visiting your feeding station once a night, it seems likely they are visiting one somewhere else as well. It is not normal for hogs to eat all their food in one sitting – as cats or dogs might.
