After trapping it and using a chain bola on one make sure before feeding it anything you injure it over half its health. Then leave it for the bola timer to finish. Once it is flying keep an eye on the health and you will see it drops super faster and will be starved in now time at all. Then just chain bola it so it stuck. Bola it a few more times as this will increase the time it cannot fly. Then feed it.

I did this on a lvl 145 and it was done in like 10mins from kibble. I did it on an official server also
