 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. Well, 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.
