COCKATRICE

"The cockatrice is a frighteningly effective blending of reptile and avian features. They congregate in packs and work together to bring down prey with a ferocity that belies their size. They aren't exclusively meat eaters, but they certainly have a preference for it, particularly horseflesh. Horse breeders have long known to watch for any signs of cockatrice packs around their ranches. If a good-sized pack gets close, an unwary breeder might wake up without a single animal remaining."
