Great question.
We call about as often as we hunt our killboxes. I wouldn't disagree with your term baiting, it's what we are literally doing. I personally think calling is a tad easier, than setting up, sneaking in and trying to kill 2 or 3 coyotes sync'd, but I enjoy both methods.
To give you more details regarding your question, usually we have two objectives to work around, Calving, and Weaning. Calving Cows are usually docile, you may spook a couple that are laid up chewin their cud every once in a while, but most of the time when they have a calf in their belly they are very complacent when we are hunting within them. I have a few calling techniques I use that work really well when we are mobile inside a calving lot.
Weaned calves are a completely different story, pulled from their mother, stressed, and easily spooked, the best time to kill around them is the first few nights after they have been sorted. They're bawling everything is loud and you can get away with a lot. 3 or 4 days later when we chase the mommas back to the pasture and the calves are quiet, that's when a house cat walking through the lot causes a stamped, let alone a Coyote pair that rip off right beside the corral, once they get a good spook, they continue the trend as opposed to never being spooked. That takes some finesse, we do a lot of deliberate shooting, driving, walking, noise making around our calves the first couple weeks of weaning, in attempt to get them used to abnormalities, that they don't experience in the pasture. Usually within a few weeks if the calves have been conditioned properly it's not really a problem anymore. However, usually we use a buffer between us and the calves, as well as suppressors etc. to help with any drastically loud noises. We also take extraordinary precautions when helping neighbors with problems.
