Hi nsp24
It’s possible some of the hogs have been predated by the badgers, but it’s also possible that they have voted with their feet and decided to move away because of the badgers. But hogs tend to ‘disappear’ for other reasons which are not obvious, too and some may even have begun to hibernate.
It’s a difficult situation, but badgers will kill hedgehogs and even though you haven’t seen it, it doesn’t mean that it hasn’t happened or might happen. I know it’s hard to do, but probably the best thing for the hogs is if you don’t encourage them into harms way by feeding them. I recall hearing about one badger who, having been accustomed to being fed next to a hedgehog, turned and killed it, despite having other food available. They are predators and it’s a natural thing for them to do. Both lovely animals but without better habitat for both, maybe you have to be content with one or the other visiting.
Sorry not to have any better suggestions.
