Courting & Nesting

Nesting lets two players — one male, one female of the same species — court, mate, build a nest, lay eggs, and incubate them to hatching. New players who join from your nest spawn as juvenilesinstead of fragile hatchlings, getting a massive head-start. It's also a prerequisite for several mutation unlocks and progression goals.

Courting & Mating

You need an adult or subadult male and female of the same species. Hatchlings and juveniles can't nest.

Find a partner
Use your vocal calls (default 1 / 2) to advertise your location. Same-species adults nearby will hear you.
Face each other and hold N
Position the two dinosaurs close, head-to-head. Both players hold N at the same time to trigger the mating animation and pair.
Verify the pairing
Open Tab → look in the Statussection. If you're paired, your partner's name will be listed.

Building the nest

Once paired, you pick the nursery spot. Anywhere on land — but pick a defensible one. Predators will hunt nests.

Place it
Face the ground where you want the nest. Press N, then B to build.
Gather debris
Use your sniff ability to locate twigs nearby. Pick them up with G, walk them to the nest, and deposit with E. More debris = warmer nest = faster incubation later.

Gestation & laying eggs

Females only. You can gestate before or after pairing — doing it ahead of time saves real-world minutes once you've found a mate.

Start gestation
Open Tab → click the Nest icon. Pick how many eggs you want to gestate. Gestating consumes hunger + nutrients; more eggs = more drain.
Wait the timer
Takes a few minutes. You can keep playing normally — just don't die or burn through your food reserves.
Lay them
Sit on your built nest. Follow the on-screen prompt (typically E) to lay the eggs. They appear in the nest immediately.

Incubation & hatching

Eggs need to reach 100% incubation before another player can hatch from them. Temperature is everything.

Keep it warm
Sit on the nest yourself, or have your mate take turns. More debris piled on the nest also helps. An unattended nest cools fast and incubation stalls.
Set Public or Private
Open Tab → Nest menu. Public = anyone on the server in the hatchling selector can request to join your nest. Private = a passcode is generated; only players you share it with can request.
Accept hatch requests
When a player on the character-select screen requests your nest, you'll get a prompt. Accept it and they spawn as a juvenile of your species — skipping the fragile hatchling stage.

Quick tips & common pitfalls

• Gestate ahead of time. Females can start gestating before pairing — saves real-world minutes once you find a mate.
• Don't leave the nest. Unattended nests cool fast; incubation stalls. Tag-team with your mate so one of you is always sitting.
• Pick a defensible spot. Carnivores actively hunt nests for an easy meal. Open meadows = death. Use brush, ledges, or contested water lines for cover.
• Public fills faster. Public nests get hatch requests almost immediately on busy servers; private nests only see traffic if you share the passcode in chat / Discord.
• Eggs don't survive death. If both parents die before hatching and no one else sits the nest, the eggs cool out. Designate a backup if your species lives in a high-risk biome.
• Mutations matter. See Advanced Gestation, Parthenogenesis, and Prolific Reproduction for traits that change egg counts, gestation timers, and juvenile stats.
