How Often Should You Turn Chicken Eggs During Incubation? Complete Guide

Turning chicken eggs is one of the most important parts of successful incubation. Whether you are using an automatic egg turner or turning eggs by hand, maintaining a proper turning schedule supports healthy embryo development throughout most of the 21-day incubation period.

So, how often should you turn chicken eggs during incubation?

Chicken eggs should be turned regularly throughout the first 18 days of incubation. When turning eggs manually, many hatchers aim for at least three to five turns per day, preferably an odd number of turns. Egg turning should stop around day 18 when lockdown begins.

In this guide, you’ll learn why chicken eggs need to be turned, how often to turn them, when to stop, and which common egg-turning mistakes can reduce hatch success.

Why Do Chicken Eggs Need to Be Turned?

Inside every fertile egg, a developing embryo depends on proper incubation conditions for healthy growth.

Regular turning helps prevent the embryo from remaining in the same position for extended periods and supports normal development.

A broody hen naturally turns and adjusts her eggs throughout the day. When using an artificial incubator, this natural behavior must be replicated either manually or with an automatic egg turner.

Proper egg turning works alongside other important incubation factors, including:

• Stable temperature
• Appropriate humidity
• Proper ventilation
• Healthy fertile eggs
• Correct lockdown conditions

Ignoring any one of these factors can potentially reduce hatch rates.

How Often Should You Turn Chicken Eggs?

When turning chicken eggs manually, many hatchers aim to turn them at least three to five times per day.

Turning more frequently may also be appropriate when following the recommendations for your specific incubator and hatching method.

The most important factor is maintaining a consistent schedule.

Avoid turning eggs only once per day or leaving them in the same position for extended periods.

Why Should You Turn Eggs an Odd Number of Times?

When manually turning chicken eggs, an odd number of daily turns is often recommended.

For example, you might turn eggs:

• Three times per day
• Five times per day
• Seven times per day

The reason is simple.

If you turn eggs an even number of times at regular intervals, they may remain in the same position every night.

Using an odd number of turns helps alternate the side on which the eggs spend the longest overnight period.

When Should You Start Turning Chicken Eggs?

Egg turning should begin early in the incubation process.

If you are using an automatic egg turner, follow the instructions provided by the incubator or turner manufacturer.

For manual incubation, establish a regular turning schedule from the beginning and continue consistently until lockdown.

The early stages of embryo development are particularly important, making proper turning practices essential.

When Should You Stop Turning Chicken Eggs?

Chicken egg turning generally stops around day 18 of incubation.

This marks the beginning of the lockdown period.

During lockdown:

• Stop turning the eggs.
• Remove or disable the automatic egg turner if required.
• Position the eggs for hatching.
• Adjust humidity appropriately.
• Maintain stable temperature.
• Avoid unnecessary incubator opening.

The final days allow chicks to position themselves for the hatching process.

What Happens If You Don’t Turn Chicken Eggs?

Failing to turn eggs properly can interfere with normal embryo development.

Potential problems may include:

• Embryos sticking to internal membranes
• Abnormal development
• Poor positioning for hatch
• Increased embryo mortality
• Reduced hatch rates

Occasionally missing a single turn does not automatically mean the hatch will fail.

However, consistently inadequate turning can create serious problems.

Can You Turn Chicken Eggs Too Much?

When eggs are handled properly, frequent gentle turning is generally less concerning than failing to turn them enough.

However, excessive handling can create other risks.

These include:

• Rough movement
• Accidental dropping
• Temperature fluctuations from repeatedly opening the incubator
• Contamination from dirty hands
• Unnecessary disturbance

The goal is consistent, gentle turning rather than constantly handling the eggs.

How to Turn Chicken Eggs by Hand

Manual egg turning is simple but requires consistency.

Follow these steps:

Step 1: Wash Your Hands

Always handle hatching eggs with clean, dry hands.

This helps reduce the risk of transferring dirt, oils, and bacteria onto the shell.

Step 2: Mark the Eggs

Use a pencil to place a different mark on each side of the egg.

Many hatchers use:

• X on one side
• O on the opposite side

These markings make it easier to track whether every egg has been turned.

Avoid using harsh chemicals or inappropriate markers on hatching eggs.

Step 3: Turn the Eggs Gently

Carefully rotate each egg to the opposite side.

Avoid:

• Shaking
• Dropping
• Sudden movements
• Aggressive rotation

Gentle handling is essential throughout incubation.

Step 4: Follow a Consistent Schedule

Choose turning times that fit naturally into your daily routine.

For example, eggs could be turned in the:

• Morning
• Afternoon
• Evening

The exact schedule is less important than maintaining consistency.

Step 5: Stop Turning on Day 18

When lockdown begins, stop turning the eggs and allow the chicks to prepare for hatching.

Should You Use an Automatic Egg Turner?

Automatic egg turners can make incubation significantly easier.

Potential benefits include:

• Consistent egg movement
• Reduced manual handling
• Less frequent incubator opening
• Easier management of larger batches
• Reduced risk of forgetting turns

For people with busy schedules or larger numbers of eggs, an automatic turner can be especially useful.

However, automatic turners should still be monitored to ensure they are operating correctly.

Can an Automatic Egg Turner Fail?

Yes.

Like any mechanical or electrical equipment, automatic egg turners can malfunction.

Potential problems include:

• Motor failure
• Incorrect installation
• Eggs becoming stuck
• Improper turning angles
• Electrical problems

Check the turner regularly throughout incubation.

Never assume that it is functioning correctly simply because it is switched on.

Should Eggs Be Turned During Candling?

Eggs naturally move slightly while being handled during candling.

However, candling should not replace your normal turning schedule.

After examining each egg, return it carefully to the incubator and continue following your established incubation routine.

Should You Turn Shipped Hatching Eggs?

Shipped hatching eggs may require additional consideration because transportation can disturb or damage their air cells.

Some hatchers modify their turning practices during the early incubation period for eggs with significantly damaged air cells.

The appropriate approach depends on the condition of the shipped eggs and your incubation method.

Inspect shipped eggs carefully and use a handling strategy appropriate for their condition.

Do Eggs Need Turning Under a Broody Hen?

No manual turning is usually necessary when eggs are being naturally incubated by a healthy broody hen.

The hen instinctively moves and adjusts her eggs throughout incubation.

She also helps regulate:

• Temperature
• Egg position
• Nest conditions

However, the nest should still be monitored to ensure the hen remains healthy and the eggs are protected.

What Happens If You Forget to Turn Eggs for One Day?

Forgetting to turn eggs for a short period does not automatically mean the entire hatch will fail.

Return to your normal turning schedule as soon as possible.

Avoid aggressively rotating or overhandling the eggs in an attempt to compensate for missed turns.

Consistent incubation practices over the entire 21-day period are more important than reacting excessively to one mistake.

Common Egg-Turning Mistakes

Avoid these common mistakes:

• Turning eggs too infrequently.
• Following an inconsistent schedule.
• Handling eggs roughly.
• Forgetting to wash your hands.
• Leaving the incubator open too long.
• Failing to check an automatic turner.
• Continuing to turn eggs during lockdown.
• Shaking eggs while handling them.
• Forgetting which eggs have been turned.

Simple preparation and a consistent routine can prevent most egg-turning problems.

How to Remember Your Egg-Turning Schedule

Manual turning requires organization.

Useful methods include:

• Marking eggs with X and O.
• Setting phone reminders.
• Keeping an incubation journal.
• Using a printed incubation calendar.
• Recording every turn.
• Turning eggs at regular daily times.

Good record keeping can also help identify possible causes of poor hatch results.

How Does Egg Turning Affect Hatch Rates?

Egg turning is only one part of successful incubation.

Good hatch rates depend on several factors working together:

• Fertility
• Egg quality
• Proper storage
• Accurate temperature
• Suitable humidity
• Consistent turning
• Adequate ventilation
• Correct lockdown conditions

Perfect turning cannot compensate for severe temperature or humidity problems.

Likewise, ideal temperature and humidity cannot completely compensate for inadequate egg turning.

Successful incubation requires consistency throughout the entire process.

Frequently Asked Questions

How many times a day should chicken eggs be turned?

When turning manually, many hatchers aim for at least three to five turns per day. Follow the recommendations for your specific incubation method and equipment.

When do you stop turning chicken eggs?

Chicken egg turning generally stops around day 18 when lockdown begins.

What happens if you don’t turn chicken eggs?

Inadequate turning can interfere with embryo development, contribute to poor positioning, and potentially reduce hatch rates.

Is an automatic egg turner better?

An automatic turner can provide consistent movement, reduce manual handling, and make incubation easier, particularly for larger batches.

Should you turn eggs during lockdown?

No. Egg turning should generally stop when lockdown begins around day 18.

Will eggs still hatch if you forget to turn them once?

Missing an occasional turn does not automatically mean the eggs will fail. Resume your normal turning schedule without attempting to compensate through aggressive handling.

Final Thoughts

Understanding how often to turn chicken eggs during incubation is essential for successful hatching.

When manually turning eggs, many hatchers aim for at least three to five gentle turns per day throughout the first 18 days of incubation. An automatic egg turner can simplify the process, but it should still be checked regularly.

Once lockdown begins around day 18, stop turning the eggs and allow the chicks to position themselves for hatch.

By combining consistent egg turning with accurate temperature, appropriate humidity, good ventilation, and careful handling, you can create better incubation conditions and improve your chances of a successful hatch.
