howls would work better right now,but changing sounds usually doesnt hurt anything,as a matter of fact some coyotes have heard so many rabbit sounds,and possibly busted or got shot at and missed by the hunter that they may come inwith a change of sounds,and coyotes are very smart,but unless they are very close when you change sounds I dont think that it will hurt,and with goats around the baby goat distress on that PM might be ones lucky ticket to doggy heaven in the back of your truck.thats very good thinking to use natural sounds that they may have heard before.Even though you could call one in with a snowshoe hare in distress sound in florida,they sometimes come to the call due to simple curiosity,not hunger though they are greedy animals,they some times rush in to beat others to the food hungry or not,changing sounds could very well help you.GOOD LUCK AND MAKE THEM GOAT SOUNDS.
