Selecting and Preparing Turkey Eggs
Successful turkey egg hatching begins with selecting and preparing the eggs. Here’s a detailed guide to help ensure you have high-quality eggs for your incubator.
Choosing Healthy Eggs
Select eggs from healthy, well-fed turkeys. The eggs should be clean, smooth-shelled, and free of cracks or dents. Avoid eggs that are misshapen or have thin shells.
| Egg Characteristic | Desirable | Undesirable |
|---|---|---|
| Shell Texture | Smooth, intact | Cracked, dented, rough |
| Shell Thickness | Thick, hard | Thin, fragile |
| Shape | Oval or round | Misshapen, elongated |
| Color | Light tan or brown | White or discolored |
Storing Eggs Before Incubation
Store eggs in a cool (55-60°F), humid (75-80% humidity) environment. Keep them in a clean, well-ventilated area with no strong odors or exposure to direct sunlight. Turn the eggs daily to prevent the yolk from sticking to the shell.
Sanitizing Eggs Before Incubation
Sanitize the eggs before placing them in the incubator to minimize the risk of bacterial contamination. Wipe each egg gently with a clean, damp cloth or swab dipped in a 1:10 bleach solution (1 part bleach to 10 parts water or an egg sanitizing solution). Allow the eggs to air dry for at least 24 hours before incubating to prevent shell damage.
Setting the Temperature and Humidity
Temperature
Maintaining the correct temperature is crucial for successful turkey egg hatching. During the first 25 days of incubation, the temperature should be set at 37.5°C (99.5°F). This temperature ensures optimal embryo development and proper formation of the turkey’s organs.
Humidity
Humidity plays a vital role in egg viability and chick health. During the first 25 days of incubation, the humidity should be kept at 60%. This humidity level prevents the eggs from drying out and aids in the proper development of the embryo’s respiratory system.
Humidity Monitoring and Adjustment
Regularly monitoring humidity levels is essential to ensure optimal conditions for hatching. Use a hygrometer to measure the humidity inside the incubator and adjust it if necessary.
| Week of Incubation | Humidity Level |
|---|---|
| Weeks 1-4 | 60% |
| Week 5 | Decrease to 55% |
| Final Hatching Period | Increase to 65-70% (to aid in pipping and hatching) |
By following these guidelines for temperature and humidity, you can create optimal conditions for successful turkey egg hatching.
Monitoring Egg Development
1. Checking Egg Fertility
Candling the eggs is the first step in monitoring their development. This involves shining a bright light through the eggs to observe the contours and movement of the embryo. Fertile eggs will appear dark with visible veins, while infertile ones will remain clear or have only a faint shadow.
2. Monitoring Embryonic Growth
Candling can also be used to track the growth of the embryo over time. At 7 days, a small dark spot indicates the start of embryonic development. As the embryo grows, the dark spot enlarges and distinct features, such as the head and limbs, become visible.
3. Monitoring Egg Rotation
Regular egg rotation is crucial for the proper development of the embryo. Eggs should be rotated 180 degrees at least three times daily. This prevents the embryo from sticking to the shell membrane and ensures proper yolk distribution.
4. Monitoring Egg Humidity
Maintaining proper humidity levels is essential for successful hatching. The optimal humidity level varies depending on the stage of incubation. For the first 18 days, the humidity should be between 55-60%. During the last week, the humidity should be increased to 65-70% to facilitate shell softening.
5. Monitoring Egg Temperature
Temperature is a critical factor in turkey egg incubation. The eggs should be kept at a constant temperature of 99.5°F (37.5°C). Variations of as little as 0.5°F (0.28°C) can affect embryonic development. The temperature should be monitored regularly using an accurate thermometer. The following table provides a summary of temperature ranges at different developmental stages:
| Stage | Temperature (°F) |
|---|---|
| Days 1-18 | 99-99.5 |
| Days 19-25 | 99.5-100 |
| Days 26-28 | 100-100.5 |
Candling the Eggs
Candling the eggs is a crucial step in monitoring embryonic development and identifying any potential issues. This process involves shining a bright light through the egg to illuminate the contents. Here’s a detailed guide on how to candle turkey eggs:
Equipment You’ll Need:
- Egg candler or flashlight with a bright bulb
- Darkened room
Steps:
- Hold the egg in a horizontal position: Place the egg in the palm of your hand, with the larger end facing upward.
- Position the light source: Place the egg candler or flashlight about 3-4 inches behind the egg, aligning it with the center of the egg.
- Shine the light through the egg: Turn on the light source and gently rotate the egg while shining the light through it.
- Observe the contents: As you rotate the egg, observe the following structures:
- Air cell: A small, clear area at the larger end of the egg.
- Yolk: A suspended, dark, circular mass.
- Embryo (after day 5): A small, dark spot with veins radiating outward.
- Blood vessels: A network of fine, red lines branching out from the embryo.
- Identify normal development: A healthy embryo will appear as a small, dark spot with blood vessels radiating outward. The air cell will gradually increase in size as the embryo develops.
- Identify potential problems:
Problem Observation Embryo not visible No dark spot or veins visible Dead embryo Embryo appears motionless, dark, and shriveled Floating embryo Embryo is not attached to the yolk and floats freely Broken blood vessels Blood vessels appear broken or missing Air cell too large or small Air cell is significantly larger or smaller than normal
Troubleshooting Hatching Problems
Egg Handling
Improper handling before incubation can compromise hatchability. Eggs should be collected frequently and stored in a cool, humid environment to prevent moisture loss and cracking.
Incubator Conditions
Incorrect temperature and humidity levels can lead to hatching failures. Calibrate the incubator regularly and monitor the settings throughout the incubation period.
Egg Turning
Regular egg turning prevents the embryo from sticking to the shell and ensures even development. Eggs should be turned at least three times daily for proper embryo positioning.

Ventilation
Adequate ventilation is crucial for embryo respiration and moisture control. Ensure the incubator has proper ventilation holes to prevent excessive CO2 accumulation.
Pip and Hatch
During the hatching process, the embryo “pips” the egg by making a hole in the shell. Assist hatching only if the embryo has been pipping for over 24 hours and is unable to complete the process on its own.
Embryo Development
Embryo mortality can occur due to genetic defects, bacterial infections, or nutritional deficiencies. Monitor embryo development closely and consult a veterinarian or experienced poultry breeder for assistance if needed.
Post-Hatch Care
Once the turkey poults have hatched, they are vulnerable to dehydration and other health issues. Provide a brooder with heat, water, and feed to ensure their survival and well-being.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Hatchability | Incorrect temperature/humidity, poor egg handling, embryo mortality | Calibrate incubator, improve egg storage, consult veterinarian/poultry breeder |
| Egg Cracking | Rough handling, poor storage, nutritional deficiencies | Collect eggs gently, provide adequate calcium in diet |
| Embryo Malposition | Insufficient egg turning | Turn eggs more frequently |
Assisted Hatching
In rare cases, a turkey poult may struggle to hatch on its own. If you notice that a poult has been pipping for more than 24 hours without making significant progress, it may need assistance. Assisted hatching should be done carefully to avoid injuring the poult.
To assist a turkey poult in hatching:
- Gently remove any eggshell fragments that are obstructing the poult’s beak or nostrils.
- Use a pair of small, sharp scissors to carefully snip away any remaining eggshell that is preventing the poult from fully emerging.
- Avoid cutting the poult’s skin or membranes.
- Once the poult has emerged, use a clean, warm towel to pat it dry and remove any remaining eggshell fragments.
- Place the poult in a warm, draft-free environment, such as a brooder.
- Provide the poult with access to water and feed.
- Monitor the poult closely for the next few hours to ensure that it is breathing and eating properly.
- If the poult is struggling to breathe or eat, contact a veterinarian immediately.
Care for Newly Hatched Poults
Provide a warm, draft-free environment: Keep poults at a temperature of 95-100°F (35-38°C) for the first week, gradually reducing the temperature to 70°F (21°C) by the end of the third week.
Offer fresh water and feed: Provide poults with access to fresh, clean water at all times. Offer a high-protein starter feed specifically formulated for poults.
Vaccinations: Consult with a veterinarian to determine the vaccination schedule for your poults based on local disease risks.
Monitor health: Observe poults for any signs of illness, such as limping, lethargy, or diarrhea. Seek veterinary care promptly if necessary.
Provide bedding: Spread a layer of clean, dry bedding material, such as shavings or straw, on the floor of the brooder.
Monitor humidity: Maintain a humidity level of 60-70% to prevent respiratory problems.
Establish a lighting schedule: Provide poults with 24 hours of light for the first few days, gradually reducing the light to 16 hours of light and 8 hours of darkness by the end of the first week.
Sanitation: Keep the brooder area clean to prevent disease. Disinfect the area regularly and dispose of waste properly.
| Week | Temperature |
|---|---|
| 1 | 95-100°F (35-38°C) |
| 2 | 85-90°F (29-32°C) |
| 3 | 80-85°F (27-29°C) |
