These thing are annoying to tame they eat so slow there torpor drains so fast they knock you out on your mount and kill it I just recommend kibble because it takes so long and you cant leave it for one second because it’s torpor.
if you want to tame a giga, just tame a griffin first or any type of griffin and shoot it with longneck rifle and shocking tranq darts. and then feed it lots of bio toxin while it’s eating quetzal kibble.
If you are on crystal Isles, go to the bee cave and bring a giga and a weight carrier (skiff or wyv), kill all the bees with the giga and use the chainsaw on the hives, you will walk out with more than 600 organic poly per bee hive, up if worked for you 😃
Worst option ever for taming on mobile. You need to get too close to it to feed, and it will get spooked and run far away if you or your mount get too close. Plus, when tamed, it's only good for knocking small animals, ascendant bow + tranq arrows are WAAAAAAY better. Low health, slow move speed... Don't waste your time. This guy should get a buff or something, cause it's completely useless, wild or tamed.
