I made it so baby animals are invincible.
Llama might also be invincible? I kept killing mine on accident so I turned it off. I'll add it back some other time.
shotgun blast works! (tested in normal mode)
I think I actually still have the Llama breeding in the game. If two llamas are next to a nest they make babies. HaHa. I planned on implementing that for other animals just got busy making other things.
it might cause performance issue... especially when you can't kill them
