On island, the best way to find ovis is to take some veggie cake in your own inventory, Dino’s will eat veggie cake in their inventory, and a large carnivore Dino or Therizinosaur into the arctic and eat everything in sight. Don’t spare anything that moves. Even eat the trees (so you can see better). When stuff starts to spawn back, ovis will spawn with them. Keep an eye out, because they live mere minutes before stuff will eat them. Tame it and cryo it like your life depends on it. Have had several die in the moments between taming them and pulling out a cryopod, one with wolves, one died by Argy. Be FAST!
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. Up if this is useful
You find them (most often) up in the north biome, at the blue obelisk. As of now, they need to be born on a ceiling (One tile above where you want them), so they will not fall into the water under the map or other unaccessible places, warning, with this method they will still fall through the ceiling, but they will fall onto the foundation underneath, allowing you to claim them there. Another warning, The baby ovis needs to be claimed immediately, or else it will die of starvation, it will also have abnormally low weight, so be sure to feed it very often.
