Usually the reason for this type of hunt isn't for the fun, but it serves a purpose. They probably have issues with the population of coyotes. Coyotes are a survival specialists, they begin to over populate a rea were food is abundant. That food includes almost anything, livestock, ( chickens,ducks,rabbits, sheep,calves even domestic pets) that hurts, especially financially. Have a loving pet removed from your porch never to be seen again and see if you wouldn't participate ? The reason is to keep numbers in check not to extinct ! The important thing is,we need to remember is to mind our business and let them deal with their issues themselves. Just like us when we detect and someone stops and sticks their noses in our business where it doesnt belong.
