For raising these beautiful creatures is pretty hard, but not that hard. I’ll tell you this secret and you’ll gonna love it. If you put the Wyvern milk in a transmitter, obelisk, and City Terminal and upload it to the Ark you don’t have to worry about it spoiling until the 24 hour timer is up and I know what your thinking, but wouldn’t they dissolve when you put them in your inventory. Short answer yes they do but if your fast enough to bring the milk to your Wyvern ASAP when you transfer it into your inventory it should eat the milk.

Hope this helps,
