Prehistoric Farm Incubator: How to Hatch an Egg

You hatch eggs in the incubator at Dr. Ivy's DNA Lab on the home island. Trade a complete set of matching fossils to Dr. Ivy for an egg, follow the incubation interaction and check the countdown before you leave the lab, and wait out the on-screen countdown that appears. One recorded session shows a Hallucigenia egg needing about five minutes and a Tectalic egg needing 2 minutes 30 seconds, so expect the timer to vary by egg. When the countdown ends, collect your newborn at the hatchery and place it on your ranch.

The whole loop in order:

1. Dig at dig sites until you hold a full set of fossils for one species.
2. Sail back to the home island and go to Dr. Ivy's DNA Lab.
3. Trade the fossil set to Dr. Ivy for an egg.
4. Start the incubation in the same visit — the hatch countdown appearing on screen confirms the egg is in.
5. Wait out the timer (you can leave and do other things), then collect the newborn at the hatchery and place it on your ranch.

Where the incubator is

The incubation step lives at Dr. Ivy's DNA Lab on the home island — the same place fossils become eggs. The game's official description has you "turn them into eggs at Dr. Ivy's DNA Lab," and its How To Play puts two steps together there: "Collect a full set of fossils and bring them to Dr. Ivy to grow an egg," then "Warm your egg in the incubator and watch it hatch."

Four named things do different jobs in the hatching pipeline, and it helps to keep them separate:

• Dr. Ivy's DNA Lab — where Dr. Ivy turns your fossil set into an egg, and where you start incubation.
• The incubator — warms the egg while its hatch timer runs.
• The hatchery — where the hatched newborn is waiting for you to collect it.
• Your ranch — where you place the collected dinosaur and raise it.

Getting an egg to incubate

The incubator needs an egg first, and the documented route is a fossil trade. Dig at dig sites with your shovel — releasing when the meter is in the green gives better finds — until you hold a complete matching set for one species. In the recorded session the player only made the trip once the set was complete: "So I finally have enough Tectalic fossils. So now let's go over and create Tectalic. We're going to go back to the home uh island to create Tectalic."

At the lab, Dr. Ivy asks "Got any samples for me?" — hand over the set and the trade produces the egg on the spot: "Trade fossils for an egg. There we go. Tectalic." That fossil trade is the only egg route this page covers, since it's the incubator's documented prerequisite; other sources, such as sea reptile eggs, are catalogued on the dinosaur eggs page.

Placing the egg and starting incubation

Do it in the same visit. The flow in the game's own FAQ runs straight through: "Bring a complete fossil set to Dr Ivy to obtain an egg, then place it in the incubator." The recorded player did exactly that, incubating immediately after the trade: "Now let's incubate the egg."

You don't need to memorize a specific prompt — what matters is the confirmation. An incubation animation plays, and a countdown appears right where you stand: "Hatches in 2 minutes and 30 seconds." A visible countdown confirms timing has started. The sources do not resolve the exact placement prompt or whether every trade needs a separate manual placement action.

How long hatching takes and what affects it

Hatching runs on the countdown alone. No extra condition appears in the game's How To Play or in recorded play — waiting out the timer is the whole mechanic. The two observed durations differ:

Both numbers come from a single recorded session, and what makes them differ — species or something else — isn't stated, so treat them as observations rather than a per-species table. The game also announces the home stretch while you're away: "So, our egg will be ready in about 1 minute," and later "DNA lab be ready in about 20 seconds."

You're free to roam while the timer runs — the recorded player went fishing instead of waiting around ("Think I'll just stay here and fish until the um egg is done") and returned when the egg was about to be done. Feeding has nothing to do with this stage; "Keep your dino's belly over half full so it keeps growing" applies only after the dinosaur has hatched. Nothing in the sources documents a way to speed up incubation, and exact times can change with balance updates.

Collecting your hatched dinosaur

When the countdown ends the game flags it — "Hatching." for the first egg, and "So, our tectalic egg is ready." for the second. Head back to the DNA Lab area and go to the hatchery: "Let's go collect that egg. Going over to the hatchery... We got ticktallic." Then carry the newborn to your ranch and release it, as the player did with both dinosaurs: "Let's go place on the ranch."

From there the hatchling is yours to grow — it starts tiny and needs regular feeding. The dinosaur growth page covers the belly mechanic, and the dinosaur raising guide picks up right where hatching ends. If you're after extras elsewhere in the game, current Prehistoric Farm codes are tracked on the codes page.
