Hive attacked by a wild animal

2015-07-05-15.03.58.jpg

I have a few hives on field beans and went on Sunday to do the weekly inspection to find that something had attacked one of them. I'm guessing a badger by the looks of it as thier 3 middle didgets are thier strongest. But could also be a very brave fox but I'm sure its a badger...2015-07-05 15.03.58 Any ideas on how to deter them from attacking my hives?
