Why a Proper Egg Incubator Setup Matters
An incubator mimics the warmth and humidity a brooding hen naturally provides. Unlike a hen, however, a machine cannot self-correct. If your temperature drifts by even a degree or two for an extended period, embryo development can stall or fail. That is why understanding how to use an egg incubator correctly, before you ever place a single egg inside, separates successful hatches from disappointing ones.
Choose the Right Incubator for Your Needs
Before you learn how to hatch eggs in an incubator, you need the right equipment for the job. Incubators range from small tabletop models that hold a dozen eggs to large cabinet units designed for commercial production. Key features to look for include:
- Automatic egg turners to eliminate manual turning (see automatic vs manual turning)
- Digital thermostats for precise temperature control
- Humidity monitoring with a hygrometer
- Forced-air fans for even heat distribution
- Removable egg trays for easy cleaning and loading

How to Set Up an Egg Incubator: 10 Steps
- Read your manual. Settings and vent positions vary by model.
- Clean and dry the incubator and trays.
- Place it on a level surface in a room that stays 65–75°F, away from windows, vents and drafts.
- Plug it in and set the temperature: 99.5°F (37.5°C) for forced-air models.
- Add a second thermometer and hygrometer at egg height to check the built-in display.
- Fill the water channels to reach 50–55% humidity.
- Run it empty for at least 24 hours and adjust until readings are steady.
- Load clean, fertile eggs and note the date you set them.
- Turn at least three times a day (or switch on the automatic turner) and candle at days 7 and 14.
- On day 18, stop turning, raise humidity to 65–70%, and leave the lid closed until the chicks have hatched and dried.
The sections below explain each step. If you own a specific model, we also have dedicated guides: HovaBator Genesis 2370 setup, hatching chicken eggs in the IncuView 3 Pro, AccuHatch Pro setup and GQF 1502 setup. Also read rookie setup mistakes that kill hatches before you plug in.
Clean and Sterilize Before You Begin
A clean incubator is a productive incubator. Before each use, wipe down the interior with a mild disinfectant and allow it to air dry completely. Bacteria and mold from previous hatches can infect developing embryos, so never skip this step. Clean all egg trays and any removable components separately. Once everything is dry, reassemble the unit, and you are ready to start the setup process.
Position the Incubator Correctly
Where you place the incubator matters more than most people realize. Set it on a stable, level surface in a room with a consistent ambient temperature, ideally between 65°F and 75°F (18°C to 24°C). Avoid placing it near windows, heating vents, or air conditioning units, as drafts and temperature swings make it much harder to maintain steady internal conditions.
Proper ventilation is also critical. Developing embryos consume oxygen and release carbon dioxide. Make sure the incubator's ventilation holes are not blocked, and that the room itself has adequate air circulation. Poor ventilation is one of the most overlooked factors in troubleshooting egg incubators. Plan for outages too: our guide on what to do if your incubator loses power is worth reading before you set eggs.
Set the Temperature and Humidity, and Let It Stabilize
Run the incubator empty for at least 24 hours (up to 48 is better) before adding eggs. This allows the internal temperature to stabilize and gives you time to make adjustments.
Best Incubator Settings for Chicken Eggs
- Temperature: 99.5°F (37.5°C) for forced-air incubators; about 101°F to 102°F (38.3°C to 38.9°C), measured at the top of the eggs, for still-air models
- Humidity: 50% to 55% relative humidity during incubation (days 1 to 18)
- Lockdown humidity: 65% to 70% for the final three days before hatching
Use a separate, calibrated thermometer to verify the reading on your built-in display. Digital thermostats can drift slightly over time, so double-checking accuracy is always a good habit. Our guide to choosing and calibrating a digital incubator thermometer shows how.
Incubation Settings by Bird Type
| Bird Type | Temperature (Forced-Air) | Humidity Before Lockdown | Lockdown Humidity | Stop Turning | Hatch Time |
|---|---|---|---|---|---|
| Chicken | 99.5°F | 50–55% | 65–70% | Day 18 | 21 days |
| Duck | 99.5°F | 55–60% | 65–75% | Day 25 | 28 days |
| Quail (Coturnix) | 99.5°F | 45–50% | 65–70% | Day 14–15 | 17–18 days |
| Turkey | 99.5°F | 50–55% | 65–70% | Day 25 | 28 days |
Starting points only. Your incubator's design and your local climate can shift the ideal numbers, so follow your manufacturer's instructions first. Hatching quail? See our quail incubation guide.
How to Control Humidity in an Egg Incubator
Humidity control is where many new hatchers struggle. Too little moisture causes the air cell inside the egg to grow too large, making it difficult for the chick to position itself for hatching. Too much humidity keeps the air cell too small, and chicks can struggle to breathe and hatch. Here is how to manage it effectively:
- Water channels and reservoirs: Most incubators have built-in troughs. Fill more channels to raise humidity; cover some to lower it.
- Use a hygrometer: Never rely on guesswork alone. A digital hygrometer gives you accurate, real-time readings.
- Add a damp sponge: If you need to raise humidity quickly, place a clean, damp sponge near a vent opening.
- Ventilation affects humidity: Opening vents lowers humidity; closing them raises it. Use this relationship to fine-tune your settings.
Understanding how to control humidity in an egg incubator is one of the most valuable skills you can develop as a hatcher. Small, consistent adjustments beat dramatic corrections every time. If your readings keep drifting, our egg incubator humidity control guide explains when an automatic controller such as the HumidiKit is worth it, and our guide to maintaining humidity in an incubator covers every species. Browse all humidity control accessories.
Select and Load Your Fertile Eggs
Only use fertile eggs from healthy, well-nourished breeding stock. Collect eggs that are clean, properly shaped, and free of cracks or unusual blemishes. Store them at around 55°F to 65°F (13°C to 18°C) with the pointed end down for no more than seven days before setting them in the incubator.
How to Put Eggs in an Incubator
- Let stored eggs warm to room temperature for several hours before setting them.
- Wash your hands first, and handle eggs as little as possible to protect the shell's natural coating.
- In an incubator with a rolling or tilting turner, set eggs in the turner racks as the manufacturer directs, usually on their sides or with the large end slightly up.
- If you turn by hand, lay eggs on their sides or set them with the large end up.
- Never set eggs with the pointed end up, because it lowers hatch rates.
Make sure your egg trays fit your incubator and egg size, and shop turners and replacement trays if yours need replacing.
Turning Eggs Throughout the Incubation Period
Egg turning prevents the embryo from sticking to the shell membrane and promotes even development. Eggs should be turned at least three times per day, and ideally an odd number of times, so the egg rests on alternating sides each night.
Most modern tabletop incubators come with automatic turners that handle this for you. If you are turning by hand, mark each egg with a pencil on opposite sides so you can track which way each egg has been rotated.
Stop turning eggs three days before the expected hatch date. This is the "lockdown" phase, when chicks begin moving into position for hatching. The incubation period for chicken eggs is 21 days.
How to Use an Automatic Egg Incubator
An automatic incubator controls temperature, and often turning, for you, but you still need to do a few things:
- Follow the instructions for your model. Preset thermostats, such as the one on the IncuView 3 Pro, are set at 99.5°F. Other models have an adjustable set point.
- Fill the water channels and check them every day or two. Water levels drive humidity.
- Check the built-in display against a second thermometer before you set eggs and again partway through the hatch.
- Turn off the turner on day 18 (some models stop automatically three days before hatch) and lay out the eggs flat, or leave the tray in, as your manual directs.
- Keep the lid closed during lockdown. Each opening drops heat and humidity.

Chicken Egg Incubation Timeline, Day by Day
| Day | What to Do |
|---|---|
| Before day 1 | Clean the incubator, run it empty for 24 hours, check readings with a second thermometer |
| Day 1 | Set eggs, record the date, start turning |
| Days 1–17 | Hold 99.5°F and 50–55% humidity, turn at least three times a day, keep water channels topped up |
| Day 7 | First candling: remove clear (infertile) eggs |
| Day 14 | Second candling: remove eggs with no development |
| Day 18 | Lockdown: stop turning, raise humidity to 65–70%, stop opening the lid |
| Days 19–20 | Chicks begin to pip. Do not help them |
| Day 21 | Hatch day. Leave chicks in the incubator until dry and fluffy, usually 12 to 24 hours |
Egg Candling to Track Development
Egg candling is the process of shining a bright light through the shell to observe embryo development. It is the best way to identify infertile eggs or early embryo deaths before they contaminate the rest of the batch. A cool LED candler such as the Incu-Bright makes it quick and safe.
Candle your eggs for the first time at around day 7. Look for:
- A visible network of blood vessels, which indicates healthy development
- A dark mass (the embryo) moving within the egg
- A clear interior with a faint ring, which may indicate a dead embryo
- A completely clear egg, which is likely infertile and should be removed
Candle again at day 14 to assess continued development. Remove any eggs that show no signs of life, as they can rot and potentially explode, introducing harmful bacteria to the rest of your hatch. Do not candle after lockdown begins.
The Lockdown Phase and Hatching
Three days before your hatch date, stop turning the eggs, raise the humidity to 65% to 70%, and minimize how often you open the incubator. This is the lockdown phase, and stability is everything at this stage.
You may notice eggs rocking slightly as chicks begin to position themselves. This is completely normal. The chick will first "pip," creating a small hole in the shell, then slowly work its way around the egg over 12 to 24 hours before fully emerging. Resist the urge to help unless a chick has been pipping for more than 24 hours without progress, and read our guide on how to help a shrink-wrapped chick first.
Leave newly hatched chicks in the incubator until they are dry and fluffy, usually 12 to 24 hours. They do not need food or water immediately since they absorb the remaining yolk before hatching. Then move them to a warm brooder: see our baby chick care guide and brooders.
Common Egg Incubator Troubleshooting Issues
Even with the best preparation, problems can arise. Here are the most common issues and how to address them:
| Problem | Likely Cause | Quick Fix |
|---|---|---|
| Low hatch rate | Incorrect humidity or temperature | Check both with a second thermometer and hygrometer |
| Temperature swings | Poor placement | Move the incubator away from drafts and windows |
| Chicks stuck in the shell | Low lockdown humidity | Raise humidity to 65–70% before day 18 |
| Bad smell in the incubator | Rotten egg | Candle: remove the affected egg immediately, and disinfect |
| No embryo development | Infertile eggs or wrong temperature | Verify breeding stock and incubator temperature from day 1 |
| Power cut | Outage | Keep the lid closed and follow our power outage guide |
Temperature spikes or drops: Check the thermostat calibration and ensure the incubator is not near heat or cold sources. A faulty heating element may need replacement (see replacement parts).
Low hatch rate despite good development: Often caused by humidity being too high during the main incubation period. Review your humidity logs and adjust accordingly.
Chicks are fully developed but unable to hatch: This usually points to low humidity during lockdown, which causes the inner membrane to dry out and stick to the chick.
Foul odor from the incubator: Remove all eggs immediately, candle them to identify the problem egg, and disinfect the unit before continuing.
Eggs not developing after day 7 candling: Verify your source of fertile eggs and confirm the incubator temperature was accurate from the start.

FAQs (People Also Ask)
Q: How do I set up an egg incubator for the first time?
Ans: Clean it, place it on a level surface away from drafts, set it to 99.5°F, fill the water channels to reach 50–55% humidity, and run it empty for at least 24 hours before adding eggs. Check the display against a second thermometer. See the 10-step checklist above.
Q: What temperature should I set my egg incubator to?
Ans: For chicken eggs in a forced-air incubator, set 99.5°F (37.5°C). In a still-air incubator, set it to about 101°F to 102°F, measured at the top of the eggs. Always follow your manufacturer's instructions.
Q: What humidity do chicken eggs need in an incubator?
Ans: Aim for 50–55% for days 1 to 18, then 65–70% for the last three days (lockdown).
Q: How long should I run an incubator before adding eggs?
Ans: At least 24 hours, up to 48, so temperature and humidity are stable before you set eggs.
Q: How often do I turn eggs in an incubator?
Ans: At least three times a day, ideally an odd number, until day 18 for chicken eggs. An automatic turner does this for you.
Q: Can I open the incubator during incubation?
Ans: Briefly, for candling or adding water, but keep it to a minimum. Do not open it during lockdown unless it is necessary, because each opening drops heat and humidity.
Q: When should I stop turning the eggs?
Ans: Stop turning on day 18 for chicken eggs (three days before hatch). Duck and turkey eggs stop on day 25, and quail eggs on day 14 or 15.
Q: Can I make my own egg incubator?
Ans: You can, but homemade incubators struggle to hold a steady 99.5°F, and a small temperature error can ruin a batch. A reliable ready-made tabletop incubator starts at about $80 and usually costs less than losing a few hatches. If you build your own, you still need an accurate thermostat and hygrometer.
