For anyone wondering, ovis can eat mejoberries after they have been tamed (and bred). No need to feed the babies vegetable cake too. They love mejoberries just as much as any other herbivore.
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.
