Can someone please tell me how long it takes for a Wyvern to fully mature on ‘single player’ settings, I’m relatively new to the game and I just want to know if I need to worry about milk or healers such as Daeodons or snow owls. I know they can last a little over 3 hours without food but I’m not sure if that is enough to grow them. As I said before I am playing on 5x single player settings.
