So, the ovis has been heavily nerfed, it now only yields about 2 mutton per wild one and caps at around 50 mutton for fully imprinted, max level, health pumped sheep the effort is not worth the reward it needs to be changed back
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.
