Well, I caught them redhanded so to speak. I followed a trail of feathers over neighboring fence. Toprail had scratches from cat climbing w chicken. Finally found bird in some brush. I heard a little noise and when I looked up there were two bobcats looking at me @ 15 ft away. Pretty cool really if they hadnt just killed all my banties but one wild rooster, then my big blue bramah hen. They didnt get exited. Just cruised away. Ive since built a covered run. Sorry about my typing, im on my mobile.
