my grandparents lost almost their entire flock this morning. 8 hens dead. 4 were still there but are not chewed. They just have tiny sores on their back from claws maybe? The other 4 are gone and there are feathers everywhere. Would a hawk do this? Even a pair? There's no sign of any predators at all other than the obvious chicken massacre. I just find it odd that a hawk would leave corpses. Any time I have ever lost chickens to Hawks they carried them off and anyone left behind was terrified but unhurt. We live in Oregon.
