There are a few people in our area who have pet deer. One person just had 3 of her deer shot during hunting season. They were in a (very high) enclosed fence, with signs all around! Fortunately, they found the "hunter" who shot them, and he is being prosecuted.
I would die if that happened to babies I raised and had been caring for. My grandmother had a sorrel horse shot and killed by a deer hunter about 40 years ago. She never allowed us to ride in the woods deer season because of it.
