On Wednesday night something and without a doubt it was badger or badgers broke into my sister in laws hen run and slaughtered 5 of her 8 hens. Despite defences being reinforced they were back again last night moving quite big stones to regain entry, no victims this time for a good job. A security light has no been fitted and , and trip wired bell. Anything else to be done, an electric fence is too expensive an option. This is in Scotland would I be able to get permission to create a permanent cure?
