 Most animals that God has created have some kind of defensive mechanism to protect themselves from an enemy. Not sheep. There have been known instances of a raven or a crow swooping down on the head of a sheep and plucking out its eyeballs. And that's a horrible thing. But let me ask you something. What's the sheep going to do? Bark? What's he going to do? Emit a noxious odor? What's he going to do? Claw the bird to death? He's not going to do anything because he's a sheep. And sheep are defenseless.
