Well 40fan, it's a good thing to think about,,, killing more yotes. Instead of using bait and calling together, try just baiting. I've pulled dead calves out of this one dairy farmers barn in Illinois, and put them on a tree line bout 200yrds. back of his barn. I've done it twice in feb. & march, I got three dogs that way, but never had any luck calling at the same time. I sorta camped out in a line of rolled bails. They do tend to hit bait at night, but if it's cold you can getem to hit it in the daylight. If there is any coyote police out there,,, it is legal to bait coyotes in Illinois.
