X2... I'm not sure what kind of hawk killed my hen. I did see it, and it was small. It couldn't fly away with the hen either. It killed her up against the house and was eating her neck when we found her. We pulled into the driveway and there it was, it didn't even fly away until my dad got out of the car (which was only about 4 feet from the hawk) and went after it. Then it came back later looking for the chicken. It was a Red tail that wounded our other hen. Now they get a lot less free range time.
