When I first got my Kune-Kune weaners they got out a few times and I could not find out how. Mildred went walk about where as George stayed closed to the barn. We double checked the electric fence and that was working well. In the end I spent the morning watching Mildred and she had found a hole that a badger had dug under the fence that we could not see due to a big bunch of nettles. Once dealt with problem solved but she was always looking for places to escape, think she thought it was a great game.
