Trapping around livestock and pets leaves you with basically 2 options. Sit up all night with your rifle and wait for the predator Purchase Live Catch Traps so if a pet or livestock is caught it is not harmed. Do not use biddy (Chicken) wire. Use rat wire, and cover the roof of chicken coupe w/rat wire as well, then place a pole extending 2 ft out of the center, place a fox trap at the top of the pole. No more Owl problems. For wolves, foxes, etc. use a wooden block and in bead a razor blade in the center of it, then pour some animal blood around the blade. Cruel, Or you could build a dog kennel (couple hunting dogs inside) around your Chicken coups and let them handle the poachers directly.
