Just so you know on xbox I'm on single player by the way on rangnorock, you cant tame ovis's with rockarrot. I tryed it didnt work so dont believe the stuff were you can tame it with rockarrots.
You should use Ovis for a mutton farm because mutton is like a less effective type of kibble. Most dinos Love mutton so this is a very useful way to use these!
If you wanna get wool without having to get ovis by just geting vegie cake make a cage with dino gate then get a argy to transport it into the cage then just simply shear it with scissors.
