Yesterday a noon I noticed that the chickens were all in their pen after I'd let them out a couple hours before I thought to my self "that's odd" they are usually out in the yard running around. Then I heard a loud chirping sound so I went out to investigate thinking that maybe one of the neighbors dogs might have gotten one of the chickens, then just as I got on the other side of the house and rounded the corning to the back yard I see this hawk flying over head and I realize that it's a warning call.
