This spring when I had a predator problem, I was deathly afraid it was a cat I had seen in my fenced in yard where the coop is. I love cats. I think cats are the only animal I love more than chickens haha! Needless to say I absolutely did not want to kill it. So I put out a live trap halfway in my coop, halfway out so it appeared that there was an easy entry into the coop. You know what I caught? A great horned owl lol!!! The last thing I expected!!! I live in AR too and I can tell you, your predator may be the last thing you expect until you catch it red handed. (or red-pawed, or red winged haha!) Good luck confronting it. I have to say though, if it were a stray dog without an owner and a mission to eat my chickens, I'd follow the three S's as well...I'm not 100% sure it was dogs. But i've never seen a raccoon around my place. These dogs however, are almost always present. I've put heavier latches and snaps on the latches. I dont think a raccoon, dog or any other 4 legged creature will be getting these open.
