Coyote pups don't usually approach people. I am wondering if it isn't sick as well as having a broken leg. Is the leg dangling, is the pup holding it off the ground, or is the pup trying to use the leg a little? If the break isn't too severe, it will eventually mend itself. The closest wildlife rehabilitators to you are over in Schuyler County: Sandra Marquis, Rushville, 217/322-6066 Patricia Mitchell, Rushville, 217/322-3837 If you think the pup needs to be put down, you should get ahold of the Illinois Department of Natural Resources district wildlife biologist. Dean Corgiat 217-285-2221. Good luck.
