The Andrewsarchus gives live birth after mating, skipping the egg-incubation step entirely. Gestation takes approximately 4 hours and 59 minutes at default rates.

The baby Andrewsarchus takes approximately 2 days and 9 hours to fully mature at default rates - requiring significant patience. The most labor-intensive part is the baby phase (0–10% maturation) when it can't use a Feeding Trough yet.

Each baby inherits stats from both parents with a chance of mutation - +2 wild levels to a random stat plus a color change. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

Raising a baby Andrewsarchus involves three maturation phases: Baby (0–10%) lasts ~347 min and requires constant hand-feeding. Juvenile (10–50%) spans ~23h - it can eat from a Trough now. Adolescent (50–100%) takes ~29h - continues eating from troughs, nearly fully grown.

Don't skip imprinting - each successful imprint boosts the Andrewsarchus's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Imprint requests include cuddling, walks, and specific kibble - check the wiki for which kibble to stockpile.

The raising calculator above shows exactly how much food you need for each maturation phase of the Andrewsarchus. Expect ~347 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.

The multiplier feature helps plan large-scale Andrewsarchus raises by totaling food across all babies. Different food types have different spoil timers - factor that into which food you stockpile.
