Yeah, coy-dogs can be a touchy subject! Rickyrick you are right on with the sounds. They are always looking to fill their bellies & with the pups geting ready to hit the ground the pup distress will also provoke a response! You may also try some lone howls but make sure to keep them on the higher pitched side. You want the resident coyotes to think they can whoop the intruder not run from it! Also, if they are using the same trails on a regular basis, you can set up an ambush. Sort of like a deer hunt but for coyotes! Just bark at one when you get it in the sights! They will usually turn broadside for the perfect shot! Make sure to take pics to share with the forum!
