The question was how do I prevent a kingsnake from eating my goose eggs and I said kill it! I have speckeled king snakes and I never killed one and have told the kids never to kill one but I have never had any problems out of them. I have found them at night eating copper heads and that's why I like them. If it is what is eating your eggs I don't know how else to prevent it from getting your eggs other than catching it and relocating him or keep your geese in a snake proof pen. We have tons of 6' chicken snakes and my brooders and 2 grow out pens both 8'X8' are made of 1/2X1/2" wire. Never had a snake problem in them.
