Turkey Egg Incubation Calculator
This turkey egg incubation calculator finds the expected poult hatch date instantly. Enter the date you set the eggs to calculate the incubation timeline, candling schedule, and lockdown date.
Quick Answer
Turkey egg incubation takes 28 days on average, consistent across heritage and commercial breeds alike. Enter your set date above to calculate the exact expected poult hatch date.

How to Use This Calculator
Enter the date you set the eggs in the incubator. Because turkey incubation length barely varies by breed, the calculator's estimate is highly consistent regardless of which breed you select. Click Calculate Due Date to see the expected hatch date and a full milestone timeline.
Poults are more sensitive to temperature and humidity swings than chicks in the final days of incubation, so precise conditions matter especially during lockdown.
How Long Do Turkey Eggs Take to Hatch?
Turkey eggs take 28 days to hatch, one full week longer than chicken eggs. Days 1–7: the embryo begins forming, visible on candling as a network of blood vessels. Days 7–14: steady growth continues; poult shape becomes recognizable. Days 14–28: rapid growth fills the egg; lockdown begins around day 25 with humidity raised to 75% ahead of hatching.
Signs of Healthy Incubation Progress
- Day 7 candling: visible blood vessel network and dark embryo confirm fertility.
- Day 14 candling: egg appears mostly dark, embryo movement often visible, air cell clearly enlarged.
- Day 25 lockdown check: egg should be almost entirely dark with a large, well-defined air cell before you stop turning.
- Pipping around day 26–27: followed by zipping and full emergence typically by day 28.
Incubation Period by Turkey Breed
| Breed | Avg. Incubation (Days) | Notes |
|---|---|---|
| Broad Breasted White | 28 days | Commercial meat breed; standard timing |
| Bourbon Red | 28 days | Heritage breed; standard timing |
| Royal Palm | 28 days | Heritage breed; standard timing |
| Narragansett | 28 days | Heritage breed; standard timing |
| Heritage (general) | 28 days | Heritage breed; standard timing |
Temperature & Humidity Guide
- Temperature: 99.5°F (37.5°C) forced-air.
- Humidity, days 1–25: 55–60% relative humidity.
- Lockdown, days 25–28: raise to 75% relative humidity.
How Turkey Eggs Compare to Other Poultry

| Goose | 30 days | 2 days longer |
| Duck (standard) | 28 days | Same |
| Turkey | 28 days | — |
| Chicken | 21 days | 7 days shorter |
| Quail | 17 days | 11 days shorter |

How We Calculate Turkey Egg Incubation
The turkey egg incubation calculator uses the formula: Hatch Date = Set Date + 28 days. The 28-day average is derived from published poultry science research and validated by university extension programs.
Frequently Asked Questions
How long does it take for a turkey egg to hatch?
Turkey eggs take 28 days to hatch on average, and this is remarkably consistent across both heritage breeds (Royal Palm, Bourbon Red, Narragansett) and commercial Broad Breasted White turkeys — unlike chickens, breed makes very little difference to turkey incubation length.
How do I calculate when my turkey eggs will hatch?
Add 28 days to the date you set the eggs. Use the calculator above for an exact hatch date and a full milestone timeline covering candling and lockdown.
What temperature and humidity do turkey eggs need?
Turkey eggs incubate at 99.5°F (37.5°C) in a forced-air incubator. Keep humidity at 55–60% for most of incubation, then raise it to 75% for lockdown in the final 3 days — very similar to duck egg requirements, and noticeably higher than chicken eggs.
When should I candle turkey eggs?
Candle at day 7 to check for early development and again at day 14 to confirm continued growth. Poults are large-bodied, so development is usually easy to see clearly by the second candling. Avoid candling after lockdown begins around day 25.
Why do turkey eggs sometimes fail to hatch?
The most common causes are the same as for other poultry: incorrect or fluctuating temperature, low humidity during lockdown (causing poults to stick to the shell membrane), infertile eggs, or eggs stored too long before setting. Turkey hens and toms also have lower natural fertility rates than chickens in some flocks, so a somewhat lower hatch rate from fertile-appearing eggs isn't unusual.
How does turkey egg incubation compare to chicken eggs?
At 28 days, turkey eggs take a week longer to hatch than chicken eggs (21 days) — the same incubation length as standard duck eggs, though turkey eggs need chicken-level humidity in early incubation before the duck-like humidity rise at lockdown.
