I have a member of my family that lives nearby, and their dog keeps coming back and attacking my chickens. This has happened three times and every time they promise to put the dog up. But this only lasts a few days and then it is out again. I have lost one nice hen and had three more hens and my main rooster chewed up severely by this dog. I am to the point of shooting the dog if it comes back. Any suggestions would help. They are crazy about their dog, but my chicken have a right to live too, especially on my property.
