If you have a batch of turkey eggs in the incubator and you are counting days. How long do turkey eggs take to hatch? Turkey eggs take 28 days to hatch. That is a full week longer than a chicken egg, which catches a lot of people off guard, especially anyone used to the 21-day chicken schedule. Set your calendar for four weeks, not three.
The 28 days is the easy part. Getting healthy poults out at the end depends on holding the right temperature and humidity, turning the eggs correctly, and knowing when to stop. Here is the full schedule.
Key Takeaways
How Long Do Turkey Eggs Take to Hatch?
Turkey eggs take 28 days to hatch, and that holds true whether they are under a broody hen or in an incubator. It is a fixed feature of turkey development, so there is no way to safely speed it up. Compared to the poultry most people start with, that is a week longer than chicken eggs at 21 days, and dramatically longer than quail, which we cover in our guide to incubating the much faster quail egg.
Both heritage and broad-breasted turkey eggs run on the same 28 day clock, so the breed of turkey does not change the timing. If you are still deciding which type to raise, our comparison of heritage versus broad-breasted turkeys covers the differences that actually matter, though incubation length is not one of them.
Because turkey eggs are larger and their shells and membranes tougher than a chicken’s, the hatch itself can also take longer once it starts. A poult may take considerably more time to pip and work its way out than a chick does, so patience at the end is part of the process.
Temperature and Humidity for Turkey Eggs
Steady conditions matter more than any single setting, and temperature is the one you cannot get wrong. For a forced-air incubator, the kind with a fan, hold 99.5 degrees Fahrenheit for the entire incubation. Even short swings above 102 or sustained periods below 98 can kill developing embryos or cause deformities, so a reliable incubator and a separate thermometer to double check it are worth the small investment.
Humidity runs in two stages, and understanding why makes it easier to get right. The developing embryo needs to lose a certain amount of moisture through the shell across incubation to form the air cell it uses to take its first breath. So you keep humidity moderate at first, then raise it for hatch.
- Days 1 to 25: hold humidity around 55 to 60 percent. This lets the egg lose moisture at the right rate.
- Days 25 to 28 (hatch): raise humidity to 65 to 70 percent. The higher moisture keeps the inner membrane from drying out and shrink-wrapping the poult as it hatches.
The science of that moisture loss and air cell development is laid out well by Poultry Extension, and it is worth reading if you want to understand what you are actually managing rather than just following numbers.

Turning the Eggs (and When to Stop)
Turning keeps the developing embryo from sticking to the inside of the shell and helps it develop evenly. Turn turkey eggs at least three to five times a day, and always an odd number of times, so that an egg does not spend every night resting on the same side.
An automatic egg turner is the easy solution and removes the main way people accidentally harm a hatch, which is forgetting to turn or opening the incubator too often. If you turn by hand, mark an X on one side and an O on the other with a pencil so you can see at a glance that every egg has been turned.
Keep turning through day 25. Then stop. That transition has a name, and it is the most important moment in the whole process.
Lockdown: Day 25 to Hatch
On day 25, you enter what hatchers call lockdown. You stop turning the eggs, raise the humidity to that 65 to 70 percent hatch range, and then, crucially, you leave the incubator closed.
Stopping the turning lets the poult orient itself into hatching position. Raising the humidity keeps the membranes pliable. And keeping the lid shut preserves that humidity at the exact moment it matters most. Every time you open the incubator during lockdown, the humidity crashes, and a sudden drop can shrink-wrap a poult that is halfway out of its shell, trapping and killing it. The temptation to help is strong, but the single best thing you can do during lockdown is nothing.
Once hatching begins, it can span 24 to 48 hours from the first pip to the last poult out of the shell. This is normal. Do not intervene because one poult is taking longer than another. Let them finish, and leave them in the incubator to dry and fluff up for a few hours before you move them to the brooder you set up ahead of time, which our guide on what you need before the poults arrive walks through.
Broody Hen or Incubator?
You do not always need an incubator. Heritage turkey hens go broody readily and will happily sit a clutch for the full 28 days, managing temperature, humidity, and turning entirely on their own instincts. A committed broody hen often out-hatches a beginner running an incubator for the first time.
The incubator wins on control and scale. It lets you hatch more eggs than a hen can cover, on your schedule, and without depending on a hen deciding to sit. Many homesteaders use both, letting hens hatch what they will and running the incubator for the rest. Either way, the 28 day clock is the same, and planning your hatch date sensibly sets up everything that follows, right through to timing the harvest at the other end.
Frequently Asked Questions About Hatching Turkey Eggs
How long do turkey eggs take to hatch?
Turkey eggs take 28 days to hatch, whether under a broody hen or in an incubator. That is a full week longer than the 21 days a chicken egg needs. Both heritage and broad-breasted turkey eggs run on the same 28 day schedule.
What temperature and humidity do turkey eggs need?
Run a forced-air incubator at 99.5 degrees Fahrenheit for the whole incubation. Keep humidity at 55 to 60 percent for the first 25 days, then raise it to 65 to 70 percent for the final hatch days. Steady temperature matters more than anything, so a reliable incubator and a second thermometer to verify it are worth having.
How often should you turn turkey eggs?
Turn turkey eggs at least three to five times a day, and always an odd number of times so they do not rest on the same side two nights running. An automatic turner handles this for you. Keep turning through day 25, then stop for lockdown so the poults can orient themselves to hatch.
When do you candle turkey eggs?
Candle turkey eggs around day 8 to 10 to check for development, looking for a network of veins and a dark spot, and remove any clear eggs that never developed. A second candling around day 25, just before lockdown, confirms which eggs are still viable and helps you spot any that have quit.
Can a turkey hen hatch her own eggs?
Yes. Heritage turkey hens go broody readily and will sit a clutch for the same 28 days, doing all the temperature and humidity management themselves. A broody hen is often more successful than a first-time incubator operator, so if you have a hen willing to sit, letting her do the work is a fine option.
