Are you guys alowed to bait yotes in OKlahoma? if not heres what may work for you. When calving starts set up an ambush over the after birth. Also works great during deer season by setting up over gut piles. Darn Coyotes can't resist and one could argue your not baiting just using what nature provides. ;D Pretty much my interpretation of the law out here in Ca is that Coyotes are a nuisance and the use of any means to exterminate them is acceptable. Correct me if I'm wrong.
I don't remember seeing anything in the regs that would prohibit baiting, and I'm sure a rancher that is having problems losing newborn calves, would let you in in a heartbeat.
I did try a little experiment this last deer season, and I will do it again this coming season. I was courious about what ate a gut pile, so when a doe was shot, I set up a trail camera on the gut pile, and fully expected to see yotes come in. The gut pile normally disapears the first night, so when I went back the next day, it was still there. About 3 days later it was gone, so I got the camera and looked at the pictures. Crows did the most to clean it up, and one opossum. On the second night a frost covered the lens of the camera and the pile disapeared. I never did get the shot of the coyote. :'( It was right at the feeder, and the deer that came in just stepped around it, and acted like it didn't bother them, so I guess me dragging the deer away from the hunting area in years past to keep from spoiling the area, just doesn't hold water. Gut em where they fall.
