So, when you first get into these creature’s domain. It might not LOOK like there are any even there. They tend to fly in and out, when you take one of those eggs though. Let’s just say, you’r gonna have a bad time.. my friend found that out the hard way.. he got an egg, as he was coming out, he was attacked by about three lightning wyverns. If you are getting chased by these things. Fly into a forest full of trees, swerve through the trees and try shacking them. Hope this was helpful to whoever Is reading this. P.S the eggs can glitch out of your inventory and go back to the original spawn point and also the eggs spoil very fast.
