I would say that I know the best way to tame one, all you need is:

4 stone gateways

4 stone gates

1 large bear trap

You will need to place the gateways in a square shape and leave just a small space between each, then put a large bear trap in the middle, now you will need to shoot the yuty and sit just behind the bear trap.

Once the yuty gets close you will need to back away a bit, the yuty should get stuck in the bear trap, now that it's stuck you should place a gate on each of the gateways so that it can't get out, now all you need to do is shoot it with tranqs through the gaps I told you to leave, and, boom you have a yuty!
