Prehistoric Farm: How to Hatch Eggs in an Incubator

Place a Prehistoric Farm egg in an unlocked incubator, follow its hatch timer, and understand the creature and size revealed afterward.

To hatch an egg in Prehistoric Farm, place it in an unlocked incubator and let its incubation finish. The incubator turns the acquired egg into a creature; it does not collect fossils or perform Dr. Ivy's egg extraction for you.

The gameplay video shows an egg with a five-minute incubation and a later hatch. Watch placement and the timer as separate parts of the sequence.

Start with an acquired egg and an available slot

Use a completed fossil set at the DNA Lab to obtain an egg, then place that egg in an unlocked incubator. Two slots start available. If a slot is occupied, capacity is the question to resolve rather than collecting a second copy of the same egg unnecessarily.

Follow the timer for the actual egg. The short tutorial-era hatch is not a universal duration. Rarity-specific timing is discussed in the incubator guide, while this page focuses on completing the placement-to-hatch task.

Inspect the creature when hatching finishes

Known size outcomes are Normal, Big and Giant. Weight is random per creature and revealed at hatch; no supported rule predicts it from an unopened egg. Do not plan a guaranteed weight or size before seeing the result.

The hatch animation reveals the outcome, but it is not the same thing as all the creature's later growth. An egg timer reaching completion does not immediately establish an Adult or Elder ranch creature.

Begin care after incubation

The hatched creature needs compatible food and Belly above half full to continue growing. Check that care condition before leaving for another long sea trip. An incubator slot becoming available again is useful for another egg, while the new creature now needs ranch attention.

Use the incubator guide for capacity and timers, or using incubator slots when arranging multiple eggs. If you still need the egg itself, use getting eggs rather than treating an empty incubator as an extraction station.
