How Long Do Turkey Eggs Take to Hatch? Day-by-Day Incubation Timeline

Turkey eggs take 28 days to hatch in an incubator, counted from the day you set them. Expect the first pips around day 27 and most poults on day 28; a cool incubator or eggs that sat in storage for a couple of weeks can push the hatch a day later.

That 28-day figure is the same in the Merck Veterinary Manual incubation table, Mississippi State University Extension and the University of Maryland’s Hatching Eggs at Home fact sheet. The parts people get wrong are the dates inside those four weeks: when to candle, when to stop turning, and when to give up on a late egg. If you want those dates worked out for you, set the eggs as a clutch on Creatures: start a clutch with a free account and it counts the days and puts each check on your list. More turkey breeds, guides and records live on the turkey hub.

Below is the full timeline, the incubator settings university poultry specialists publish for turkey eggs, why hatches run early or late, and what to do on hatch day.

How long turkey eggs take to hatch, day by day

Every published table we checked puts domestic turkey eggs at 28 days. Merck lists 28, Mississippi State lists 28, Texas A&M’s Incubating and Hatching Eggs (A. Lee Cartwright, B-6092) lists 28, and Penn State’s 4-H overview of the modern turkey industry notes that commercial poults hatch on the 28th day. Wild turkeys sit for about the same time: University of Missouri Extension’s wild turkey guide gives about 28 days.

Here is how those four weeks break down in an incubator:

• Day 0, set. Eggs go into a preheated, stable incubator after warming slowly to room temperature.
• Days 1 to 7. Turn the eggs several times a day. Early embryos are fragile, so handle gently and do not open the incubator more than you need to.
• Days 8 to 12, candle. Embryos can be confirmed easily after 8 to 12 days, according to Texas A&M. Remove clear eggs and obvious early losses so they cannot spoil.
• Day 14. Mississippi State’s hatchery management guide opens the vents an extra quarter at day 14 for turkey eggs; growing embryos use more air.
• Day 25, lockdown. Stop turning, move eggs to the hatcher (or off the turner), and raise the humidity. Both Mississippi State and Texas A&M put the turkey transfer at day 25.
• Days 27 to 28, hatch. Pipping should start within a day of the listed period, and one bird takes 10 to 20 hours from pip to out (Texas A&M figures for all species).

Day 0 or day 1?

Sources disagree about how to count, and it explains a lot of “my eggs are late” worry. Many keepers call set day “day 0” and count elapsed days; others call it “day 1” if the eggs went in before noon. Neither is wrong, but pick one, write it down and use it for every date, because a one-day difference in counting moves your lockdown and your expected hatch by a day.

Incubator settings for turkey eggs

Turkey eggs want a slightly cooler and drier set than chicken eggs. Mississippi State’s turkey row is 99°F in a forced-air incubator with an 84 to 86°F wet bulb, against 100°F and 85 to 87°F for chickens. Texas A&M lists 99.5°F and 84 to 86°F for turkeys, then 98.5°F with a 90 to 94°F wet bulb in the hatcher from day 25. Read those as a narrow target band of 99 to 99.5°F, not two different answers.

• Temperature. 99 to 99.5°F in a forced-air (fan) incubator. Still-air incubators stratify, so Mississippi State adds 2 to 3°F and measures at the height of the top of the eggs. Check your thermometer against a good reference first; Mississippi State warns that a one-degree error held for 21 days can seriously interfere with embryo growth.
• Humidity. 84 to 86°F wet bulb until lockdown, which Mississippi State equates to roughly 58 to 60% relative humidity. Maryland’s simpler version is 55 to 60%, rising to about 70% at hatch.
• Turning. At least five times a day, more is better; Texas A&M calls once an hour ideal and recommends an automatic turner. If you turn by hand, Mississippi State suggests an odd number of turns a day (3, 5 or 7).
• Lockdown. No turning from day 25, humidity up to about 90°F wet bulb or more, vents opened further, and the lid kept shut.

Follow your incubator maker’s instructions where they differ, because cabinet design changes where the warm air sits. What matters most is a steady number: Texas A&M expects a poor hatch if the temperature drifts more than half a degree from target.

Why turkey eggs hatch early or late

Temperature is the main lever. Mississippi State puts it plainly: an incubator that runs consistently warm gives an early hatch, one that runs consistently cool gives a late hatch, and both lower the number that hatch. A thermometer reading a degree high or low is the usual hidden cause.

Storage is the second. Holding eggs longer than two weeks can stretch incubation by as much as a day, per Texas A&M. Breed and egg size matter less than people expect; the published tables do not split turkeys by breed.

Mixing species is the third. A chicken goes into lockdown at day 18 and a turkey at day 25, so a shared incubator forces one batch onto the wrong schedule. The Texas A&M guide says to incubate together only eggs with similar incubation lengths. Ducks share the 28-day period (see the duck egg hatching guide), while quail and chicken eggs do not.

Before you set: collecting and storing turkey hatching eggs

The clock starts at set, but hatch rates are partly decided before that. Mississippi State’s Care and Incubation of Hatching Eggs (Dr. Tom W. Smith) gives the core rules:

• Collect eggs often (at least three times a day, more in hot weather) and do not wash dirty eggs; washing pushes germs through the shell pores. Slightly soiled eggs can still be set.
• Store them cool, about 55°F with around 75% relative humidity, small end pointing down. Texas A&M allows 55 to 65°F and says never above 72°F or below 46°F; a kitchen refrigerator is too cold.
• Set within about 7 days. Hatchability holds reasonably well for a week and then falls; after 3 weeks Mississippi State says it is close to zero. If eggs must wait longer than a few days, turn them once a day in storage.
• Let stored eggs warm to room temperature before setting (Texas A&M suggests 4 to 8 hours) so condensation does not form on the shell.

Texas A&M adds that turkey eggs are one of the exceptions that tolerate storage better than most, but it only gives a number for chukar eggs. Treat 7 days as the plan for turkeys too.

Fertility depends on the flock. Broad Breasted White and Bronze turkeys cannot mate naturally and, as The Livestock Conservancy explains, need artificial insemination to produce fertile eggs. Eggs from a backyard Broad Breasted hen with no insemination will not develop. Heritage varieties such as the Midget White turkey mate naturally, and the Conservancy’s heritage definition expects fertility of 70 to 80%. Turkey hens also store semen for a long time; University of Missouri Extension’s incubation guide says a hen can lay fertile eggs as long as 200 days after mating, so do not assume a newly separated hen’s eggs are pure from her new tom.

Buying hatching eggs. Ask whether the source flock takes part in the National Poultry Improvement Plan. The USDA APHIS reference guide describes NPIP as a voluntary federal and state cooperative program that tests and certifies breeding flocks, poults and hatching eggs for freedom from certain diseases. Rules for moving poultry and eggs between states vary; check with your state veterinarian or state NPIP agency before you ship. The chicken guide to buying hatching eggs covers more source checks that apply to turkeys too.

Candling turkey eggs

Candling tells you which eggs are developing so clear or failed eggs can come out before they spoil.

Turkey eggs are harder to candle than white chicken eggs. Their shells are cream to tan and covered in brown speckles, and Texas A&M notes that dark or speckled shells transmit less light. Use a bright, focused light in a fully dark room and hold the egg against it; the air cell and a developing embryo sit at the large end.

What you are looking for, per Texas A&M:

• Developing: a dark spot in the large end with distinct blood vessels spreading under the shell. It grows each time you look.
• Clear: the egg glows evenly with no vessels. It was infertile or never started.
• Early loss: a blood ring or smear, or a dark spot stuck to the shell, with vessels that have faded.

Brief cooling while you candle (under 10 minutes) does not harm embryos, but keep the egg away from a hot bulb; Texas A&M warns that even a brief spell at 104°F kills embryos. If a dark speckled egg is genuinely unclear, mark it uncertain and look again a few days later rather than discarding it.

A second look before lockdown is useful too: by then a developing egg is mostly dark, with only the air cell bright at the large end.

Lockdown and hatch day

At day 25, stop turning, lay the eggs on their sides in the hatcher or on the incubator floor on a surface poults can grip, raise the humidity and close the lid. If you hatch in the incubator, Texas A&M suggests cloth or rough paper (not newspaper).

Then leave it shut. Opening the incubator drops the humidity just as poults are breaking through the shell membrane.

• Pips usually start around day 27. The whole job from first pip to a poult out of the shell takes 10 to 20 hours, with long rests. Do not worry about an individual unless it goes beyond 20 hours, the Texas A&M guide says.
• Let poults dry in the hatcher. Move them to a warm brooder with feed and water once they are dry and moving, and do not leave the whole hatch in so long that early poults dehydrate. A good rule of thumb from Texas A&M is to remove them when more than 90% are dry.
• Late eggs. Texas A&M treats eggs still unhatched one day past the expected period as finished. If your incubator ran cool or the eggs were stored long, a later hatch is plausible, so candle stragglers before deciding.
• Do not pull poults out of the shell. Attempts to help often fail, Texas A&M notes. If you are worried about a pipped poult, ask an experienced keeper or a veterinarian.

Call a veterinarian now if newly hatched poults are gasping, cannot stand, or show signs of illness across the batch. The guide to finding an avian vet explains how to line one up before hatch week.

Brooding poults is close to brooding chicks: steady heat they can move toward or away from, dry bedding, clean water in a shallow fount and feed from the start. The raising baby chicks guide covers the brooder basics. Ask your feed supplier or county extension office which starter feed suits turkey poults rather than assuming a chick ration fits.

Hatching turkey eggs under a broody hen

The timing does not change under a hen. University of Missouri Extension describes wild turkey hens laying a clutch of 10 to 12 eggs, then sitting about 22 to 23 hours a day for about 28 days, with poults following the hen to find food within two days of starting to pip.

If one of your own hens goes broody, count the same 28 days. The broody hen guide covers nest setup, feeding a sitting hen and keeping other birds from adding eggs. Mark the eggs you set so you can tell them from later additions, and count your 28 days from the day she began sitting steadily, not from the first egg laid.

Keep the hatch record on Creatures

A hatch is easy to lose track of: which hen laid which eggs, how many were clear at candling, how many pipped and how many made it. Creatures keeps that in one place with egg clutches, which are live for poultry and free with a signed-in account.

1. Set the clutch. Start a clutch, choose turkey, say which eggs they are (one hen, a flock, existing stock or bought eggs, or not sure), enter how many you set and the set date, and choose “In an incubator” or “Under a broody hen”. You also pick your day-count convention (day 0 at set, or day 1 if set before noon), so the dates match how you count.
2. Follow the schedule. For turkeys Creatures uses a 28-day period with a day 27 to 28 hatch window, a first candling check around days 7 to 10 and lockdown at day 25. The clutch shows which day you are on, and the checks appear on your Today list so they are not forgotten.
3. Record candling. Count what you saw: developing, clear or uncertain. “Uncertain” is a useful answer on speckled turkey shells. You can label individual eggs if you want to follow a few closely.
4. Record the hatch. Enter how many hatched and how many did not, add first pip and hatch times if you noted them, and mark hatching complete when it is finished. The clutch keeps the hatch numbers even as poults later move on.
5. Give poults profiles when they need them. Create profiles from the brood for birds you keep individually, or keep the hatchlings together as a brood group or join them to a flock without naming every poult. The births and litter guide explains how offspring connect to parents, and the count group guide covers keeping poults as a group. The turkey name generator helps when a poult earns a name.

If you keep chickens too, the chicken hatch records guide walks through the same idea for a chicken batch, and the chicken incubator guide covers incubation basics on the 21-day schedule. For other poultry on the same platform, see how long goose eggs take to hatch and how long quail eggs take to hatch.

FAQ

How long do turkey eggs take to hatch?
28 days in an incubator at 99 to 99.5°F, with first pips usually around day 27. Under a hen it is also about 28 days from when she starts sitting steadily.

Can turkey eggs hatch at 26 or 30 days?
A day early or late is common and usually points to incubator temperature (warm runs early, cool runs late) or long storage before setting. Much earlier or later than that suggests a temperature problem worth checking with a second thermometer.

When do you stop turning turkey eggs?
Day 25. Mississippi State and Texas A&M both give day 25 for turkeys, three days before the expected hatch.

Can I hatch turkey and chicken eggs together?
Not easily. Chicken eggs lock down at day 18 and hatch at 21; turkey eggs lock down at day 25. Running both on one schedule shortchanges one batch, so use separate incubators or stagger the sets with a separate hatcher.

Will eggs from my Broad Breasted turkey hatch?
Only if she was artificially inseminated. Broad Breasted turkeys cannot mate naturally, so their eggs are infertile without it. Heritage breeds mate naturally.

How long can turkey hatching eggs be stored?
Aim for 7 days or less at about 55 to 65°F, small end down. Hatch rates fall after a week and drop sharply with longer storage.

Do this next on Creatures

You have eggs coming or poults on the way. These are the steps in the order most keepers need them.

• Add your breeding birds first: Add your turkey (the hen and tom behind the eggs) so the clutch and any poults connect to them. You can start signed out and finish free signup in the same sheet. The adding an animal guide walks through it.
• Record what happens: Add a record for a mating, a health check or a note on the flock. The form opens for visitors; a free account saves it. See adding a record and reminders and upcoming care.
• Watch for turkeys and poults: Save a turkey listing alert and get an email when turkeys are listed. Enter an email to sign up in the dialog; an alert does not guarantee a match. Saving searches explains how alerts work.
• Represent your farm: If you raise turkeys as a farm or hatchery, create your organization profile. Guest signup is part of the flow.
• See what is listed now: Browse turkeys on the marketplace, then ask the seller about the flock’s health testing and records.
• Find farms to talk to: Explore the breeder directory for trusted breeders and farms, and ask about NPIP participation before buying eggs or poults.
