I had one young roo and a pullet killed today. They were free ranging right in front of their tractor. My girlfriend found the chickens at 2pm and the bodies were stacked on top of each other. The chicken on the bottom was mostly eaten. All that was left was a leg and the hip bone, pieces of the breast bone, both wings, and a little bit of the intestines. The bird on top was intact except the head was severed off(only inches from the body) and it looked like a little bit of the throat had been devoured. The feathers were scattered in like a half circle right around the bodies and the bodies were only about 2 feet from the entrance to the tractor. Does this sound like a hawk to you? Do weasels attack during the day?
