The baby Rockwell takes approximately 3 days and 20 hours to fully mature at default rates - over an extremely long period, one of the longest in the game. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.

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.

Maturation has three phases: Baby (0–10%) lasts ~556 min and requires constant hand-feeding. Juvenile (10–50%) spans ~37h - it can eat from a Trough now. Adolescent (50–100%) takes ~46h - continues eating from troughs, nearly fully grown.

Don't skip imprinting - each successful imprint boosts the Rockwell's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

Planning a mass raise? The Rockwell raising calculator breaks down food needs per phase so nothing goes to waste. Expect ~556 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.

Adjust the dino count to calculate food for multiple Rockwell babies at once - essential for batch breeding operations. Match your food choice to your play schedule - longer spoil timers mean less babysitting.
