You have to hand tame the oviraptor with eggs. Some on the beach would be easiest choice due to being able to take them back to your base area with a raft. Quetzalcoatl eggs are your most likely pick due to their size. They get scared easily too so be careful when taming.
So their easy to knock out, taming it.....not that easy, they eat eggs. The larger the egg, the more efficient it tames. You can tell the size by the weight of the egg. These guys are very useful, put them on wander in your base, and they'll collect all your creatures eggs.
First off, if you're on official rates and you don't have access to a giga egg, get comfy cuz you're taming dodos for the next 2 hours. One male and as many females as you can. They have a chance of laying an egg every time they poop so even though you literally need like 200 for a mediocre Ovi, it still might be faster than waiting for another creature to pop out enough for you. Secondly, do find a way to trap it before you knock it, ANYWHERE that isn't near those dang ichthyornis birds. I had just knocked an oviraptor once when that bird swooped down and just like that I no longer had the amount of eggs I needed. It's happened with narcotics too. Just stay away from those avian beach bums. Third and last of all, the ovi will NOT hold all the eggs it needs to eat all at once. So you'll have to pay attention and keep adding eggs as it eats. This guy needs some serious babysitting while being tamed, but the buff is definitely worth it.
Using a lvl 30 ovi and a lvl 250 PT for Webern eggs, wish me luck (no joke my PT can take out a lvl 50 wyvern, I dunno if that impressive but it impressed me) one 🥾↗️ means you want to hear bout my results! This is my first ever wyvern egg run! (I’ve played ark since it came out, I’m just so lazy I just never wanted to prepare for a wyvern egg run, on my original The Island game I had 30 snails and 20 dung beetles with 5 bees, I spent time with them individually basically every day, yeah, that just shows how much I sit around irl and in ark)
