Complete Guide to Egg Incubation and Proper Incubator Operation
Successful egg incubation does not depend solely on the quality of the incubator. Even an advanced incubator cannot deliver satisfactory results without healthy fertilized eggs, suitable environmental conditions and proper care.
This guide covers general incubation principles for users of CocksMachine egg incubators. Model-specific settings and operating instructions are provided in each product's individual manual.
1. Three Main Factors for Successful Incubation
Incubation results depend on three important factors:
- The egg incubator: The machine must be in good working condition, with correct temperature, humidity, ventilation and other functions.
- Quality of fertilized eggs: Eggs should be fresh, healthy, properly fertilized and stored under appropriate conditions.
- Operator care and experience: The operator must regularly monitor environmental conditions, embryo development stages and incubator performance.
Important: Good equipment cannot compensate for poor-quality fertilized eggs or incorrect operation.
2. Choosing a Suitable Incubator Location
Room Temperature
- Place the incubator indoors.
- Avoid direct sunlight.
- Do not expose the machine to direct wind.
- Keep it away from direct airflow from air conditioners and heaters.
- Monitor daytime and nighttime temperature differences.
- Avoid room-temperature fluctuations exceeding 4°C.
Room Humidity
Room humidity is different from the humidity required inside the incubator. Do not confuse these two values.
Ventilation
- Do not operate the incubator in an enclosed space without adequate ventilation.
- Do not block air inlets or outlets.
- Avoid placing the incubator on carpets or materials that obstruct lower air openings.
- Keep the surrounding air circulation pathways clear.
Warning: Never block ventilation openings in an attempt to increase humidity.
3. Testing the Incubator Before Loading Eggs
Before starting the first incubation cycle, run the incubator without eggs for one or two days.
- Verify that the heating system works correctly.
- Check that the internal temperature reaches the required range and remains stable.
- Confirm that humidity reaches a suitable level.
- Check the fan and air circulation.
- Verify the egg-turning system according to the machine model.
- Keep all ventilation pathways unobstructed.
- Ensure that the door or lid closes properly.
If you have limited incubation experience, begin with inexpensive fertilized eggs.
4. Selecting Suitable Fertilized Eggs
The quality of fertilized eggs is one of the most important factors affecting incubation results.
- Choose fresh eggs.
- Select eggs with intact shells.
- Use eggs with a normal shape.
- Avoid excessively large or excessively small eggs.
- Ensure that eggs have been stored correctly.
- Obtain fertilized eggs from a reliable source.
Egg cleaning: According to CocksMachine manuals, do not wash fertilized eggs. If an egg is slightly dirty, gently clean its surface using a dry brush or toothbrush.
5. Storing Fertilized Eggs Before Incubation
| Condition | Recommendation in the Manuals |
|---|---|
| Maximum Storage Period | 7 days |
| Storage Temperature | Approximately 18°C |
| Relative Humidity | Approximately 55% |
| Storage Location | Dark environment |
| Refrigerator Storage | Not recommended |
Preparing Eggs for Incubation
- Remove the eggs from their storage location.
- Keep them for several hours in a room at approximately 25°C.
- Allow the temperature difference to decrease.
- Position the eggs according to the incubator's turning system.
Egg orientation: In incubators with individual egg-turning cups, position the eggs with their pointed ends facing downward. For other turning arrangements, follow the model-specific manual.
6. Understanding Setter and Hatching Stages
Setter Stage
During the setter stage, the embryo develops inside the egg. For chicken eggs, CocksMachine manuals specify approximately 18 days.
- Monitor temperature and humidity.
- Turn eggs according to the appropriate schedule.
- Maintain proper ventilation and airflow.
- Inspect incubator performance regularly.
Hatching Stage
During the hatching stage, the embryo prepares to emerge from the egg. For chicken eggs, this stage usually lasts approximately three days.
- Egg turning is stopped.
- Eggs are transferred to the designated hatching area.
- Sudden movement and temperature shock are avoided.
- The incubator door or lid remains closed as much as possible.
Note: This schedule applies to chicken eggs. Other bird species have different setter and hatching periods.
7. Temperature and Humidity for Chicken Eggs
These values are taken from CocksMachine incubator manuals. Always consult the specific model's instructions for exact settings during the different incubation stages.
Factory settings: Incubator controllers are configured at the factory. Avoid unnecessary changes to electronic settings. The values above are not instructions to manually modify factory calibration.
8. The Importance of Egg Turning
Egg turning is an important part of the setter stage.
- Follow the turning instructions for your specific incubator.
- Check that the turning mechanism operates correctly.
- Continue turning until the specified transfer time for hatching.
- Stop turning at the hatching stage according to the model-specific instructions.
Different incubator models: Some machines use automatic egg turners, while others require a manually operated lever. Do not apply one model's turning schedule to another model.
9. Egg Candling on Days 7 and 14
Egg candling helps inspect embryo development. CocksMachine manuals recommend checking eggs on days 7 and 14.
Safe Candling Conditions
- Perform candling in a dark room.
- Keep the room warm.
- Avoid strong shaking of the eggs.
- Prevent sudden movements.
- Complete the procedure as quickly as practical.
Day 7
Developing eggs should normally show blood vessels that appear as dark lines inside the egg.
Day 14
According to the manuals, approximately two-thirds of the interior of an egg with a developing embryo may appear dark by day 14.
Eggs without visible development: The manuals recommend removing transparent eggs showing no embryo development to reduce the risk of contamination. Confirm the assessment before removing any questionable eggs.
10. Transferring Eggs to the Hatching Stage
For chicken eggs, the transfer from setter to hatching generally takes place around day 18.
- Prepare the hatching area or basket according to your incubator manual.
- Stop egg turning.
- Transfer the eggs gently to the hatching area.
- Perform the transfer in a warm environment to reduce temperature shock.
- Check temperature, humidity and ventilation.
- Close the incubator door or lid securely.
- Avoid opening the incubator unnecessarily during the final days.
Hatching warning: Frequent opening of the incubator may disturb temperature and humidity and affect chicks that are still inside their eggs.
11. Chick Hatching and Initial Care
Not all chicks necessarily emerge from their eggs at exactly the same time. The manuals note that:
- Door opening should be limited during hatching.
- Humidity may increase as chicks emerge.
- Newly hatched chicks need time to dry.
- Some chicks may hatch later than others.
Drying Newly Hatched Chicks
The source manuals state that newly hatched chicks may remain inside the incubator for up to 48 hours while drying and using their remaining yolk reserves.
12. Fan Operation and Internal Air Circulation
The air circulation fan must operate continuously throughout incubation.
- Make sure the fan is running.
- Check that its speed has not decreased.
- Keep all air inlets and outlets unobstructed.
- Ensure that dust or other materials do not block airflow.
- Maintain adequate ventilation around the incubator.
Do not block essential ventilation openings to prevent humidity from escaping.
13. Cleaning and Maintenance Between Incubation Cycles
Inspect the incubator after each cycle and before beginning the next one.
- Check fan condition.
- Inspect ventilation openings.
- Inspect the egg-turning system.
- Check the water reservoir.
- Verify temperature-controller operation.
- Check the humidity gauge or humidity controller.
- Confirm that the door or lid closes properly.
- Inspect model-specific connections and components.
Cleaning products: The original manuals warn against the use of chemical cleaning products. Follow the model-specific instructions for appropriate cleaning methods and permitted materials.
Unhatched eggs: Examining eggs that did not hatch after an incubation cycle may help identify possible causes of failure.
