Hatching the wyvern eggs can be very difficult. If any of you just play scorched earth to get the Dino's and transfer over to the island or center, I have a tip that makes it easier for reading the babies. Milk only lasts so long on scorched. But on the center and island when transferred it lasts 10 hours! And 24 hours in the obelisk. So raising on the center or island map is so much easier ! Make it doable for my tribe on the center. Had to make waaaay less milk runs. Hope this helps !
Use a Daeodon’s passive healing ability to completely avoid the disasters of getting milk. Our attempts to get milk cost us many many high-leveled flyers. The passive healing results in no casualties. You just have to watch the food of the Daeodon
To know how much time need to the next feeding just do the next. Look the Food number# then that number multiply x 10, then divide /3600 and the result will be the number of hours until the next time need to be fed. F.E the food number is 1850.5 1859.5x10=18595 /3600 = 5.1 hours
