After a successful mate, the Fire Wyvern lays a fertilized egg. Incubation temperature must stay between 80°C and 90°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 4 hours and 59 minutes.

After hatching or birth, the baby Fire Wyvern matures at a glacially slow pace - plan for a multi-day commitment, reaching adulthood in about 3 days and 20 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 Fire Wyvern involves three maturation 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 Fire Wyvern'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 Fire Wyvern raising calculator breaks down food needs per phase so nothing goes to waste. The Baby phase (0–10%) takes ~556 minutes and is the most hands-on, requiring direct feeding or a Maewing.

Raising multiple Fire Wyvern 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.
