Found one of my hens still alive out in the road in front of my house. She was blind (I could not tell but it looked like she had no eyes left) and there was a large hole in her chest about 5-6 in in diameter and tissue had been picked at/eaten. I was outside for a long time and all of a sudden I just saw her flapping and screaming in the road. I suspect a hawk, but any other ideas? Need to know what kind of shot to load in the 20 guage!
