Some sets are hundreds of years old.
Badgers are nocturnal animals, foraging for food at night along hedges and wooded banks.
Their favorite foods are mice, slugs, insects, and earthworms. Although they can live to age 14, badgers often die or are killed at a younger age. When they ventured away from their sets to hunt for food, they often had to cross roads, where they were usually killed. Early fences and tunnels to prevent roadkill and allow movement were not highly successful. The fences were too low and were not anchored in the ground, allowing the badgers to climb over or crawl under them and onto the road.
