Thanks moleskins, think I will just get my game-keeper friend over to help with my extremely cocky fox, sooner rather than later! I went to check on the ewes just now and he is sitting right next to the fence in broad daylight and didn't even flinch when I shouted at him. Luckily my dog escaped from the house again and barked at him, causing him only to run a few yards away and sit watching us. When did foxes become so brave?!
