If this is your first wyvern heres some things you should know - eggs are the easy part, if you cant succesfully get an egg dont even try to raise it because milk is 10x as hard to get. Second if you are like me and you're raising your wyvern on the island map then focus on building a good structure to keep your bird in and always have at least 2 (only keep one on scorched earth at a time). And lastly dont carry anything with you when you kite wyverns to your trap as you (and your bird) will die sometimes
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.
