ARK: Survival Ascended Egg Incubation Calculator

Calculates exact incubation time and ideal temperature range for 167egg-laying ARK creatures. Set your server's EggHatchSpeedMultiplierand toggle single-player settings — the timer updates instantly with the hatch ETA. Egg temperature ranges come from the ARK Survival Ascended dossier data and tell you whether you need a campfire, A/C unit, or polar gear to keep your egg viable. Mammals (Achatinas, Daeodons, Equus, Megatheriums, etc.) gestate live and use the Breeding Calculator instead.

Temperature Reference

🔥 Very Warm (35°C+) — Wyverns, Gigas, Magmasaur. Use multiple A/C units, dimorphodons, or scattered campfires.
🔥 Warm (25–35°C) — Rex, Trike, Stego. Campfires + standing torches usually enough.
☀️ Mild (15–25°C) — Raptor, Allosaurus, Carbonemys. One campfire indoors works.
❄️ Cool (0–15°C) — Argentavis, Quetzal, Pteranodon. Shade or A/C cold mode.
❄️ Cold (below 0°C) — Snow Owl, Managarmr. Multiple A/C units in cold mode.
