Quail Egg Incubation Calculator

How to Use This Calculator

Enter the date you set the eggs in the incubator. Selecting the correct species matters more here than for other poultry — the gap between the fastest (Button Quail, 16 days) and slowest (Bobwhite, 23 days) is 7 days, nearly half the shortest incubation period itself. Click Calculate Due Date to see the expected hatch date.

Quail eggs are small and hatch quickly, so precise record-keeping of the set date matters — a day's error is proportionally larger than it would be for a longer chicken or duck incubation.

How Long Do Quail Eggs Take to Hatch?

Coturnix quail eggs take 17 days to hatch — one of the shortest incubation periods of any bird kept for eggs or meat. Days 1–5: the embryo begins forming rapidly, given how compressed the whole incubation period is. Days 5–14: steady, fast growth continues. Days 14–17: the chick grows to fill the tiny egg; lockdown begins around day 14, with humidity raised to 70% for the final push to hatching.

Signs of Healthy Incubation Progress

• Day 5–6 candling (Coturnix): a small but visible blood vessel network confirms fertility, though quail shells' speckling makes this harder to see than with chicken eggs.
• Late-stage weight check: quail eggs should lose roughly 13–15% of their starting weight by lockdown, similar to other poultry species proportionally.
• Pipping around day 16 (Coturnix): hatching itself is fast — often complete within a few hours of the first external pip, much quicker than larger poultry species.

Temperature & Humidity Guide

• Temperature: 99.5°F (37.5°C) forced-air.
• Humidity, early incubation: 45–50% relative humidity.
• Lockdown, final 2–3 days: raise to 70% relative humidity.
