After hatching or birth, the baby Hyaenodon matures over a lengthy period, reaching adulthood in about 1 day and 22 hours at 1x maturation. Hand-feeding is required until 10% maturation. After that, a Feeding Trough handles the rest.

Mutations can add +2 levels to any stat and change colors. Stacking mutations across generations is the key to min-maxed breeding lines. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

Raising a baby Hyaenodon involves three maturation phases: Baby (0–10%) lasts ~278 min and requires constant hand-feeding. Juvenile (10–50%) spans ~19h - it can eat from a Trough now. Adolescent (50–100%) takes ~23h - continues eating from troughs, nearly fully grown.

Imprinting during maturation provides permanent stat bonuses. At 100% imprint, the Hyaenodon gains 30% bonus damage and resistance when ridden by the imprinter. You'll be asked to cuddle, walk, or feed specific kibble at regular intervals during maturation.

Planning a mass raise? The Hyaenodon raising calculator breaks down food needs per phase so nothing goes to waste. The Baby phase (0–10%) takes ~278 minutes and is the most hands-on, requiring direct feeding or a Maewing.

Raising multiple Hyaenodon simultaneously? Set the dino count and the calculator scales food requirements automatically. Match your food choice to your play schedule - longer spoil timers mean less babysitting.
