YOU NEED FERT EGGS!! Levels DON’T matter!

After different attempts this worked best for me:

Step1: Solo or with a tribemate, scatter fert eggs all around nest, distanced about 3-4 foundations away from the nest.

Step2: You’ll hear/see mom attacking the egg(or tribemate can let you know) and that’s when you want to hide.

Step3: emote with the baby and if mom eats the egg it’s okay, she’ll come back and aggro on you

Step4: have your tribemate run into the nest to take over or if solo, run away leading her towards something else to aggro.

Step5: repeat the steps 2 - 4 until tamed.

After taking you can use your tamed gigantoraptor to pickup ORPHANED babies
