O.k. so let me get this straight. A male jack--- "donkey" guards a flock of chickens from coyotes? What the heck? I have never heard of this. Do they bother the chickens and do they rid all the predators? Is this a common knowledge thing? do all farmers know this? I am such a city girl. If I move to the country, would this be a wise decision, to get a jack? Now I know that a dog would guard a flock, but what other animals do this also. How the heck do they catch the coyotes? I think a jack would be so slow.
