In ASA, the Oviraptor has a setting for egg collection, and a the egg laying buff is turned on while wondering is activated. So over weight them till they the eggs weigh them down. PS they eat meat once tamed. Just keep meat in troughs or eggs will become lunch.
the oviraptor can steal eggs wiithout making the dinosuar that layed the egg angry just find a egg and lead it to the egg and it will pick the egg up!!! btw if u r planning to tame these they only eat eggs up if it is helpful!
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.
