About 20 years ago I talked to a rancher and his wife that had both cattle and sheep. They had been the last of the ranchers in the area near Medicine Bow, Wyoming that raised sheep.
One night they lost 27 sheep out of 200 to a group of coyotes.
Only a small number of the sleep had been killed for food, the rest were part of a killing spree.
The remaining sheep were shipped to market the next day.
That marked the end of their flock of sheep.
Very expensive experience I'm sure. Us city dwellers have little insight into what causes nightmares for those who supply us with our food and clothing.
We have family friends who are ranchers adjacent to Yellowstone and we've heard from them the bitter stories of their fight against the re-introduction of wolves to that park. Trying to ID a specific predator from a mostly gone carcass isn't easy and without proof the Feds just say so sorry.
