I’ve come across many of these feathery birds flying and/or walking minding their own business, they are fairly easy to tame and breed. To tame just simply knock it out using 3-5 tranqulizer darts, get some meat and put it in its inventory then sit down and relax. Just mind dire wolfs and Rex’s and other carnivores. And they are really easy to breed, just tame 2 of them, male, and female, put them both in a secure area and put them on wander then they’ll do their thing, and also it is really important to keep them to whatever temperature they need to be, simply use a campfire if they are cold and put them in water if they are too hot.
