Taming it can be a real pain, so here is a tip for you:

Get a low lvl one first.

for example:

(lvl 45 (+22 taming bonus)) +88 potential lvl ups = 155

Now you can just claim 150 Gigantoraptor baby’s with full lvl boost :)

If you really hate the mini game you could also get a lvl 5, but then you need 2 steps since the Gigantoraptor can only claim baby’s with a lower lvl than their own.

For example:

(lvl 5 (+2 taming bonus)) +88 potential lvl ups = 95
