You want a high level oviraptor and put all levels into melee. Melee damage affects the size of area they pick up eggs. Then put your ovi on lowest follow distance, line them up next to a fridge and put railings round them. You can move the eggs to the fridge really easy then not have to worry about the wanderer skedaddling
I dare you to raise one!! They are savage if you got two high lvl parents (about lvl 140ish) and you get imprinting on it. The thing will become an adult with about 230% melee and basically one chomp any bronto!!! But on the down side you loose your job and your girlfriend
I was flying around the swamp at night and saw this massive black shadow, being the intelligent young man that I am I flew over to it on my pterodactyl because I had no clue what it was. Scariest 20 seconds of my life.
