I have barnyard cats but I am so LUCKY that my cats DO NOT chase, hunt or kill any of my chickens. If anything, the chickens run after, chase, attack, peck, beat up and abuse my poor barn cats and the barn cats run the heck away and hide. My cats know who is boss and knows who runs the barnyard and it's not the cats. I also keep my barnyard cats fed at all times, to they are never hungry, so they do not have the desire to run after and kill the cats, even though it's their instinct to hunt and kill. I guess I'm just lucky.
