Instead of laying eggs, the Onyc carries its young through a gestation period. Gestation takes approximately 4 hours at default rates.

After hatching or birth, the baby Onyc matures over a lengthy period, reaching adulthood in about 1 day and 4 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 Onyc involves three maturation phases: Baby (0–10%) lasts ~168 min and requires constant hand-feeding. Juvenile (10–50%) spans ~11h - it can eat from a Trough now. Adolescent (50–100%) takes ~14h - continues eating from troughs, nearly fully grown.

Don't skip imprinting - each successful imprint boosts the Onyc'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.

Planning a mass raise? The Onyc raising calculator breaks down food needs per phase so nothing goes to waste. The Baby phase (0–10%) takes ~168 minutes and is the most hands-on, requiring direct feeding or a Maewing.

Raising multiple Onyc 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.
