I had problems with a critter killing 5 beutiful australorm pullets that I had raised from chicks,they had just started laying and something found a weak place in the wire and pushed its way in,,killed all 5 in one night,,since then I have installed two strands of electric wire around the bottom of my run,,same for the top,and placed steel wire aprons around the bottom and nailed it down,and placed cinder blocks around the wire,,and purchased 4 of the nite guards and placed them around my coop and run,and for good measure i crisscrossed barbed wire on the door about 2 inches apart,3 feet up on the door,and put small padlocks on the coop door and run gate,I have outdoor nest boxes too so i chained them down and added padlocks to them too,,and I also keep a 20 guage pump shotgun close by my door,I felt like I let my birds down by not protecting them from night prowlers,,I have killed two foxes and one coyote in one month since.if a varmit is on my property,day or night,attempting to harm my chickens ,it will get shot,,on sight,,3 inch magnum buckshot works wonders,,relocating don,t work,that only causes problems for someone else,,good luck and keep the rifle handy
