To get Wyvern eggs (on Valguero) just tame a Quetz and built some auto turrets on it. Then y choose a Flyer y want to use (I used a Lymantria) and put it into passive mode then Flyer to the Snow Area and watch the Wyverns falling of the sky. Then look for an Egg and when its safe take your chosen flyer and take it.
Don‘t land the quetz. After that Flyer back to the quetz (it should be in front of the Egg and land on it. Go home and welcome your baby.
I got multiple eggs with this method and Wisch y‘all good luck
I tamed a 150 perfect argy, beefed him up to 20k health and 800% damage, straight up yoinked a level 165 wyvern egg(which i didn’t know existed, thought it went it 150), annihilated all the angry losers, hatched it, forgot I needed milk and it died, don’t be me
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
You can raise a wyverns without any milk. Tame a Daedon to heal the wyvern so it won’t die from hunger, and if you want full imprinting just put it in a cryopod then throw it back out if it asks for milk, that will change what they want
