I know that dogs are a major chicken predator and hope to keep my 3 from being evil w/ the birds. But I was wondering how effective the dogq is as a gaurdian of the flock. Several webpages extoll the dogs as protectors. I hear mine barking throughout the night at something, so I believe they will ward off 4-footed chicken stealers. What have all of you found dogs to be, good or bad sentries?
