For the first time, we have lost a grown hen to a daytime predator. Initially you would think red tailed hawk, but they hunt by sight and in open areas. This chicken was found snug in between several privet bushes, so densely covered we couldn't find her for the longest time. Even walking right by her, within a foot, I could only see her if I was squatting and lifting branches up. Very dense! Not a popular place for hawks. Plus, a hawk diving or falling into there would have dropped a feather or two, but none were found. The hen was mostly intact on her side. Head and top of the neck were skinless and meatless. Mostly just connective tissue and bone. Honestly looked "plucked", pecked, or nipped at. Very small chunks ripped out many times.The stomach was torn open under a wing but intestines were still present. The crop might have been gone, hard to tell. Other organs looked intact. Any thoughts? Did the other chicken eat her? Did they kill her and eat her? These are free range Basques chickens. They have a large pasture, wooded area, and garden to pick through. I doubt they are missing anything in their diet. They certainly aren't bored.
