Well, I'm not going to get into the valuation of the sheep, I have no idea what they sell for. I agree that the county is stuck with the law that is on the books, if they want to change it for future livestock damage, I guess they can.
Don't see how the county can be held liable for wild animal damage, such as coyotes. I've thought county or state governments should place a bounty on coyotes and encourage the good ol boys to hunt them. We just had some plumbing work done by a man that came here from New Zealand. He said possums got there by some means and have no natural enemies so the multiplied greatly. Local government back in the day had a 25 cent bounty on them, determined by bringing in possum tails, and guys would wander the roads at night, shine the possums eyes, and shoot them.
Anyway, sympathy for the losses.
