I would try to call them in,you can get a mouth call for about ten dollars and you will probably be suprised at how effective it is if you have coyotes in hearing range when you start calling.You dont have to sound like an expert caller to call in a coyote,just be quiet while setting up and control your scent and dont let them see you walking in which sounds like you already got a lot of this going for you since you are already seeing coyotes while hunting,and most of all be ready when you blow the call,they can cover a lot of ground fast and be almost in you lap before you are able to raise your gun.Baiting is sometimes effective,I have bunches off trail cam pictures of coyotes eating a deer carcass tied to a fencepost but all are at night and we cant kill them at night here in KY,make sure to tie or chain your bait to a tree or post,they will drag a full size deer carcass off after they find it.GOOD LUCK!!
