Quail Egg Incubation Calculator
This quail egg incubation calculator finds the expected hatch date instantly. Enter the date you set the eggs and select your species — Coturnix, Bobwhite, California, or Button Quail — since incubation length varies more dramatically by species in quail than in any other common poultry.
Quick Answer
Coturnix quail egg incubation takes 17 days on average — Bobwhite quail take about 23 days. Enter your set date above and select the species to calculate the exact expected hatch date.

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.
Incubation Period by Quail Species
| Species | Avg. Incubation (Days) | Notes |
|---|---|---|
| Coturnix (Japanese) | 17 days | Most common domesticated quail; fastest common cycle |
| Button Quail | 16 days | Smallest species; shortest incubation of all |
| California Quail | 22 days | Wild North American species |
| Bobwhite | 23 days | North American wild species; longest incubation |
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.
How Quail Eggs Compare to Other Poultry
| Species | Avg. Incubation (Days) | Vs. Coturnix Quail |
|---|---|---|
| Goose | 30 days | 13 days longer |
| Duck (standard) | 28 days | 11 days longer |
| Turkey | 28 days | 11 days longer |
| Chicken | 21 days | 4 days longer |
| Quail (Coturnix) | 17 days | — |

How We Calculate Quail Egg Incubation
The quail egg incubation calculator uses the formula: Hatch Date = Set Date + Average Incubation Days. The 17-day Coturnix average and species-specific estimates are derived from published poultry science research.
Frequently Asked Questions
How long does it take for a quail egg to hatch?
Coturnix (Japanese) quail eggs — the most commonly kept species — take 17 days to hatch, one of the shortest incubation periods of any common poultry. Bobwhite quail take considerably longer at 23 days, California quail around 22 days, and tiny Button Quail hatch fastest of all at just 16 days.
How do I calculate when my quail eggs will hatch?
Add 17 days to the set date for Coturnix eggs (23 days for Bobwhite). Because the difference between species is so large relative to the short incubation period, selecting the correct species in the calculator above matters more for quail than for almost any other poultry species.
What temperature and humidity do quail eggs need?
Quail eggs incubate at 99.5°F (37.5°C) forced-air, the standard poultry setting. Humidity should run 45–50% for most of incubation, then rise to 70% for lockdown in the final 2–3 days — quail eggs are small and can dry out faster than chicken eggs if humidity runs too low.
Why is Coturnix quail incubation so much shorter than Bobwhite?
The difference reflects genuine species biology, not incubator settings — Coturnix (Japanese quail) are a domesticated species selectively bred for extremely rapid reproduction, while Bobwhite are a North American wild species with a longer natural incubation period. Mixing up the two is one of the most common mistakes new quail keepers make, since a 6-day gap is enormous relative to a 17-day total incubation.
When should I candle quail eggs?
Quail eggs are small and often speckled or dark-shelled, making candling harder than with chicken eggs. Candle around day 5–6 for Coturnix (day 7 for Bobwhite) to check for early development, and again a few days before lockdown to confirm growth. A strong, focused candling light is essential.
How does quail incubation compare to chicken and duck eggs?
At 17 days, Coturnix quail eggs hatch faster than any other common backyard poultry species — 4 days quicker than chickens (21 days) and 11 days quicker than standard ducks (28 days). This rapid cycle is why quail are popular for producers wanting fast turnover and multiple hatches per season.
