Do not try to hatch an egg near the wyvern trench. when u drop the egg the wyverns will come out and try to kill u. But the wyverns that come out are only females you can use this to ur advantage to get milk.
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.
