Coyotes get the blame for just about everything that goes wrong in nature right up to and including rising gasoline prices. There really isn't any evidence relayed by the poster that points specifically to a coyote as the suspect. As a larger predator coyotes are far less efficient turkey killers than bobcats. Far more harm is done to overall turkey populations by nest raiders like raccoons, skunks, and crows; hawks & owls snatch little ones and sometimes adults too, plus cold wet weather is a killer for eggs and first hatched. My first passion in the outdoors is predator calling and I kill my share of coyotes and some more, but I do understand the way the hunt and they aren't the worst of the turkey killers out there truth be known.
