i knock them out with one tranq arrow. You can also just ounch them. Then out berries in their inventory. I made a zoo with them. They provide eggs. I like that they are loud. The zoo is a huge thatch structure filled with them. Make sure you fill a feeding bin with berries for them.
Encountering this creature will mean your imminent death. If you want to take this you need a tek trap, as they can break metal. It can outrun almost all creatures. It will take approx. 350 shocking tranq darts for a level one and 1240 for a 180.
