The incubator is the quietest step in Prehistoric Farm and the one players most want a number for. The official description gives it one sentence: you warm the egg in an incubator until it hatches. That is the entire published specification.
Where eggs come from
There are two confirmed sources, and they lead to different kinds of creature.
The DNA Lab route. Dig fossils on the islands, complete a full set, and take it to Dr. Ivy’s DNA Lab. The lab grows the set into an egg. This is the main line of progression and the one your first dinosaur almost certainly comes from.
The Sunken Grotto route. The description mentions sea-reptile eggs in the Sunken Grotto, reached through the diving side of the game. These are a separate find rather than a lab product — you are collecting the egg itself rather than manufacturing it.
Either way the egg then needs warming. Nothing in the official text suggests the two routes use different incubators.
Time your own hatch
Start a timer the moment the egg goes into the incubator, stop it when it hatches, and record what you see. Two independent observations of the same egg type is a fact; one is an anecdote. Send yours to the desk and we will add dated rows here.
Incubator planning from your own observation
There is no built-in hatch time here. Put in a number you measured and this tells you what a batch of eggs costs you in real minutes.

Planning around an unknown timer
Treat incubation as background work. Whatever the real duration turns out to be, the pattern that wastes the least time is the same: put an egg in before you go digging, not after. Incubation is the only part of the loop that progresses while you are doing something else, so leaving a slot empty while you are out on a boat is pure loss.
The other habit worth building now is to have the next fossil set nearly closed before the current egg hatches. A grown dinosaur needs feeding to keep developing, so the moment one hatches your attention gets split. Staggering the work beats batching it.

Questions
Frequently asked questions
What is the hatch time in Prehistoric Farm?
To be announced. No hatch timer has been published by Project Mirvy for any egg, and the figures circulating elsewhere are not traceable to a source. Time your own with the stopwatch tool on this page.
Where do eggs come from?
Two confirmed routes. Dr. Ivy's DNA Lab grows an egg from a complete fossil set, and the Sunken Grotto contains sea-reptile eggs you can find directly.
Can I speed up an incubator?
Not stated. Whether there is a boost, a Robux skip or an upgrade path is unpublished, so we have not described one.
