In the Roblox simulator Prehistoric Farm by Project Mirvy, the incubator is the crucial bridge between unearthing ancient bones and raising living dinosaurs on your ranch. Once you extract DNA by trading a completed fossil set to Dr. Ivy, you must warm your egg in the incubator before bringing your newborn creature to life.
This guide details exactly where to find the Prehistoric Farm incubator, how to prepare and place eggs, observed hatch countdowns, and how to collect your new dinosaur at the hatchery.
Where to Find the Incubator
The incubator is located inside Dr. Ivy's DNA Lab on the main spawn island (Home Island), situated close to your ranch.
When managing your dinosaurs, note that the hatching pipeline is split across four distinct stations on Home Island:
- Dr. Ivy's DNA Lab: The laboratory where Dr. Ivy exchanges your completed fossil sets for dinosaur eggs and where incubation begins.
- The Incubator: The warming station inside the lab that holds your egg while its countdown timer runs.
- The Hatchery: The nearby collection area where your newborn dinosaur waits once the incubation countdown reaches zero.
- Your Ranch: The open pens where you place, feed, and raise your hatched creatures from Newborns to rideable Elders.
How to Get an Egg and Start Incubation
An incubator requires an egg, and the standard path in Prehistoric Farm runs entirely through fossil excavation. You cannot place raw fossil pieces straight into the incubator.
- Dig for Fossils: Travel to a period island (such as Cambrian Island) by boat. Approach a dig site, hold down your tool action, and release when the meter hits the green zone for better excavation results.
- Complete a Fossil Set: Dig until you assemble the required number of matching fossils for a single species (for example, five or six specific fossils depending on the period creature). Dig results are chance-based, meaning empty "No fossil" attempts will happen alongside fossil finds.
- Trade with Dr. Ivy: Return to Home Island and enter the DNA Lab. Speak to Dr. Ivy ("I bring fossils back to life. Got any samples for me?") and choose the option to trade your completed fossil set for an egg.
- Place the Egg in the Incubator: Interact with an open incubator slot to begin warming the egg. A visible countdown timer will appear on screen confirming that incubation is active.
Players start with two incubator slots available in the lab. For players wanting to hatch larger clutches simultaneously, the official Roblox game store lists game passes for Incubator 5 (299 Robux) and Incubator 6 (399 Robux).
Incubator Timers and What Affects Hatch Speed
Once an egg enters the incubator, hatching is governed strictly by a countdown timer. You do not need to perform mini-games or stay glued to the incubator while it warms.
Recorded Hatch Times
Incubation times scale depending on the egg or species rarity. Gameplay sessions have recorded the following actual countdowns:
| Dinosaur Egg Observed | Incubator Countdown | Source |
|---|---|---|
| Hallucigenia (Starter Cambrian Egg) | ~5 minutes | Recorded gameplay observation |
| Tectalic / Tiktaalik (Devonian Egg) | 2 minutes 30 seconds | Recorded gameplay observation |
Third-party community guides list estimated general brackets ranging from 1 minute for Common eggs up to 20 minutes for Legendary eggs, but actual in-game timers displayed over your specific incubator slot are the only definitive measurement.
What to Do While Waiting
Because the incubation countdown runs automatically in the background, you are free to leave the lab and pursue other activities:
- Go Fishing: You can grab a fishing rod at the docks, purchase bait, and catch fish like mackerel, sardines, or swordfish to earn coins.
- Dig More Fossils: Sail back out to dig sites to begin working on your next fossil collection so you have another egg ready when a slot frees up.
- Tend to Hatched Dinosaurs: Feeding existing ranch dinos keeps their growth timers advancing while new eggs warm up.
For immediate hatching, the official game pass shop offers a "Skip Hatching Cutscene" pass for 49 Robux, but standard timer reduction primarily relies on waiting out the clock or watching for developer-hosted event boosts.
Collecting Your Dinosaur at the Hatchery
When the incubator timer hits zero, the game prompts you that your egg is ready. However, the dinosaur does not appear automatically on your ranch or directly inside your active hotbar inventory.
- Visit the Hatchery: Head over to the hatchery station situated by the DNA Lab area.
- Collect the Newborn: Interact with the station to claim your hatched creature.
- Place on Your Ranch: Carry the tiny Newborn to your ranch enclosure and set it down.
Once placed on the ranch, the incubator's job is complete. From this point forward, you must maintain the creature's hunger: according to official developer instructions, a dinosaur's belly must remain over half full for it to continue growing through its life stages (Newborn, Juvenile, Subadult, Adult, and Elder).
Frequently Asked Questions
Can you put Sunken Grotto sea reptile eggs in the incubator?
The official game description mentions sneaking into the Sunken Grotto to steal sea reptile eggs. However, no official documentation or recorded gameplay verifies that stolen sea reptile eggs can be placed into Dr. Ivy's incubator or hatched into ranch dinosaurs. All verified incubation mechanics currently apply strictly to fossil-traded eggs from Dr. Ivy.
Do dinosaurs starve or fail to hatch inside the incubator?
No. Eggs inside the incubator require no food, water, or manual upkeep. Feeding mechanics only begin once you collect the newborn from the hatchery and place it inside your ranch pen.
How do you unlock more incubator slots?
Players begin with two functional incubator slots. Expanding beyond your default capacity requires purchasing extra incubator game passes from the game's store menu or the official Roblox experience page.
