Can you imaging this coming over the hill? Now, with battery operated remote control devises of today, once could maybe make this work. But think of this. Animals usually don’t like the sound of guns. Infact have you ever shot a gun by an animals ear. They get a little jumpy. And sheep can jump. So I imagine as one triggers the remote control, can you visualize this sheep jumping the fence and running, maybe right back at the guy holding the remote control. Maybe this is not the best idea.
