yeah, works great for turkeys! no , but i have had foxes stalk them while turkey hunting. if he was mt coyote, hed have been dead six times. he'd run off, id call, hed come right back.
if you need a cheap easy decoy, get 2 squirrel tails a big white feather, and somekind of fur, about 6 inches in size. get a dowel rod or an arrow shaft, get a fur ball on top, and hand the squirrel tails and feather from it with some fishin line. the tails and feather give it movement with a little wind. and for some reason they seem to really key in on that white.
good luck
