The fastest way I've been able to grow and help people grow is... Step 1: Is getting a good group and coordinating with voice chat.. Step 2: Put all your babies in home caves close to crater. Step 3: Bring all your Birbs to crater on a server that's pvp activate and everyone is killing each other.. Step 4: Steal trophies off the dead or out of the water or trick a carni into biting and dropping trophies.. Step 4: Juggle them all in a safe spot so they don't de-spawn while your friends bring them to homecave. Step 5: Pick up the trophy from your friendly birdo.. stack as many trophies as you can, waiting for a half hour in between quest turn-ins. Step 6: rest overnight with about 4 or 5 trophy quests ready to turn in.. Step 7: Wake up and profit!! Don't claim the quests right away and don't fly in on accident as a bird, or you have to wait 30 minutes, and you miss out on the well-rested xp buff. Should be noted that you can't do this solo cause the trophy will say it belongs to another dino.. What you can do... is have your alternate account on phone do the flying.. but I'd recommend using a controller on mobile so you can precisely steal trophies.. I got my EO to sub adult in a day on official servers using the xp buff and the griefers to my advantage... I never even left my cave except to pick-up the trophy outside. Bby stayed safe with bird on lookout duty! It's a fun method, too, cause you're close to the action and get to see a lot of fights
