Face the facts. Chickens are way up on the food list, despite our names and inclinations to make them pets, and engage their personalities. We have lost barn cats to Hawks that carry Kits off , and of course small Hens. While we were building houseing it was disheartening to count one less every coupla days. Neghbor dogs are controlled or eliminated, just the same as any other predatory creature. Fenced or not, they WILL find a way in, and take what they want to survive. You will not educate them otherwise.
