I dispatched an old goat that was dying of colic. I took it up the hill I drive past every morning. Nothing touched it, not even the birds.

I trapped on this sheep farm. And they always had some dead stock. The coyotes would actually walk right over the dead sheep but never ate on them. But by placing my CRs 30 or 40 yards away from the carcasses I caught some coyotes. But the carcasses went un touched. I don't know If they were medicated or not never asked.

I pulled the traps I had in the area and moved them a 1/4 mile. Absolutely no pics of coyotes since the cow was dumped.

Will see if the move pays off.

I think greed can be a factor. If one hits the others follow.
I've done better on approaches, at times 1/2 mile or more.
(thanks adc guys)
Even if not hitting them they check them.

Ask you neighbor to bury it or partially bury it or cover with old compost, silage, rotten hay and see what happens.....

I have witnessed this for decades, but for some reason, if that same cow loaded with medicine or whatever is buried, the coyotes seem to work them better.......

With a warm open winter the canines and even others don't need to feed on carcasses yet. They can wait until things get more like hard winters or even to be used during pup raising. Lot easier for the yotes to feed pups with half rotten meat as it is much easier and quicker to digest. I don't think it has a lot to do with disease in the carcass. I can see medications causing different odors or taste and that may delay the usage until the carcass "matures".

My uncle used to have a ranch in Mayerthorpe. He shot 27 coyotes and 2 wolves off a dead horse in a weekend. Maybe they prefer horse. LOL
