It's going to be tough if they've been out there harassing coyotes. The ones they got obviously aren't coming to a call. And the ones that got away ain't either if they hear a vehicle. I'd walk in and start calling.
Can't really say on the hogs but they ain't dumb either. If I learn that land I have permission to call on has been trapped on or had people chasing coyotes on it, I pass and let those people have at it. But here the landscape is different too so if you know of places where they wouldn't or couldn't get to that's where I'd go. Might be a longer and more treacherous hike to call but there's no sense in calling where you know the coyotes aren't at for sure.
