Rusty--those coyotes are survivors. They will eat most anything that comes along, as you have probably discovered. Several years ago, I made a bad shot and hit a young coyote in the gut. Finally put him out of his misery and took some time to study the contents of his stomach, etc. He had remains of snakes (garden variety), safflower seeds (an oil crop up here in ND), grasshoppers, mice, brush rabbits, grass, little sticks, and feathers (don't know what bird, probably grouse or hen pheasant feathers) in his stomach.
Thanks for the comeback on your setup. It sounds like you have a real good system worked out there. The old pointy PVC pipe would never work here in North Dakota. You would have to use dynamite to make a hole to put the pipe in the frozen ground. That might have a tendency to scare away the critters that were within a mile of your calling site.
