When it comes to raising a wayvern you must be prepared to loss a good amount of sleep, but it is easier to raise highe level ones since there food will be higher and it will take it longer time for it to drop to zero
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.
