Wyvern Eggs require a very high temperature to hatch. Choose a reliable supplier to quicklyBuy ARK Wyvern. A minimum of 15 Campfire will be needed to reach the required temperature. More fires may be required during the night, to accommodate the lower ambient temperature. It takes around 3 days and 20 hours to grow to an adult and they will take Wyvern Milk for imprinting and petting but can be rare prompt.

Using Adobe structures can greatly reduce the amount of heat or insulation sources needed. On Scorched Earth, Air Conditioners are greatly discouraged because of their costs and impossibility to run during Electrical Storms.

Another viable solution to hatch Wyvern Eggs is to keep them close to a Dimetrodon leveled Up in Damage to provide powerful thermal insulation. Some ARK PVP Dinos have very high levels. Multiple Dimetrodons can be used to stack their insulation up to entirely replace Campfires and Air Conditioners.
