More badger evidence

Actually there is plenty of evidence of badgers - there are holes appearing all over the fields. I'm beginning to worry about damage to orchids and fungi which must be taking place given the extensiveness of the diggings. However what caught my eye was a collection of badger fur. I have no idea of how or why. Do badgers fight each other? Was there a confrontation with a fox? Did it catch the fur on some fencing? Was it scratching an itch?
