I agree a Coyote will eat anything to survive. Here in Texas this time of year we have Grasshoppers everywhere and the Coyotes love them. I have even seen them eat Cow dung in the Winter after Cows have been on fresh oats. Here in Texas we grow little Sweet Corn, most of it is Field corn which is very different that Sweet corn. I would believe that they would eat fresh sweet corn if nothing else was around. I still bet it is mainly Coons and hogs.
