This morning is the second time a coopers hawk has attacked my chickens. Its first attack, about 3 weeks ago was successful. It ate the neck and head of one of my young hens that was getting ready to lay. Since then it has visited only to be scared away when I step out the back door. It came back 3 times the week of its kill, then disappeared until today. It always goes for the younger hens it seems like, and they are always the hens that free range. So far both attacks were at the property line with the hen pinned against my yard fence. It did not kill the hen today, but it would have if I didn't go around the corner of my house where it was sitting on her. The hen had no feathers plucked and no visible external wounds so I think the hawk just did pin her down when I got there. But she was bleeding from her mouth so I am thinking that means internal injuries?. I'm not sure if she will make it but she is standing and drinking water so far. Also I have about 5 grown roosters that also free range and they were all hiding under the porch. They are no longer considered useful and will be gone. The only reason I knew something was going on is because my turkey and guinea fowl were going nuts, not the roosters.
