Try to lure out some of the wyverns with a very fast Flyer then head back in and grab and egg then fly as fast as possible because all of the surrounding Wyverns will be aggroed, which is one of the reasons it is good to lure some away first
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.
