Keith, here's a real life story for you, straight from the horse's mouth. The guy we used to lease land from in Hazelhurst, Mississippi, used to plant the most beautiful green fields you'd ever seen.
Years ago, a guy down the street's cows got out, all 13 of them and wound up on our guy's land on one of his large green fields.
He corralled the cows into a fenced in area. Later that evening the guy who owned the cows knocked on his door to get his cows.
Our guy told him sure, you can have them. That will be $39.00, $3.00 a head for grazing my green fields, a pretty good deal if you ask me.
The guy paid up and his cow's never got loose again.
Keith, don't even think about shooting another person's animals, you will get into a ton of trouble.
I say corral them like our guy did and charge him a fee to get 'em back.
