This morning we found a dead hen in our yard. Her neck was broken, she was still warm which told us that it had happened recently. I don't think it was any sort of predator as I was in the yard at the time. We are thinking that it was possibly our young speckled Sussex cockerel as the hens normally fight to get away from him. Before I turn him into stew, I'd like to know if anyone else has heard of a rooster breaking a hen's neck?
