Digital Household Egg Incubator — Installation, Operation and Maintenance
The CocksMachine Digital Household Egg Incubator is designed for straightforward operation. However, successful incubation requires proper environmental conditions, healthy fertilized eggs and careful monitoring.
This English guide is based on the latest supplied 11-page operating manual for the Digital Household incubator.
It covers egg selection, automatic egg turning, temperature control, humidity management, water filling, candling, hatching and routine maintenance.
Please read all instructions before placing fertilized eggs inside the incubator.
Digital Household — Main Technical Specifications
The following technical information is taken from the supplied Digital Household manual.
Important model feature: The Digital Household incubator uses a motor-driven egg-turning mechanism with interchangeable egg cups for different bird species.
General Operating and Safety Instructions
- Run the incubator for one or two days before placing eggs inside to make sure the machine is functioning correctly.
- If you have limited experience, begin with inexpensive fertilized eggs instead of valuable eggs.
- Do not install the incubator outdoors, under direct sunlight or in an area exposed to wind.
- Maintain a room temperature between 23°C and 27°C. The manual warns that operating outside this range may reduce incubation efficiency.
- Keep the machine away from direct cold or hot airflow produced by air conditioners or heating systems.
- Avoid enclosed rooms with inadequate ventilation.
- Fresh-air openings are located underneath the incubator. Do not place the machine on carpets, rugs or floor coverings that may block these openings.
- Never block the ventilation channel on the incubator lid.
- Maintain the recommended room relative humidity of 50–55%.
- Avoid room-temperature fluctuations exceeding 4°C.
- Monitor daytime and nighttime temperatures.
Critical ventilation warning: Never obstruct the air inlets underneath the incubator or the ventilation opening on its lid.
Do not open the incubator during the final three days of incubation, except when an emergency requires it. This is particularly important after the first chicks hatch.
Electronic settings: Do not interfere with the incubator's electronic systems. The temperature controller has been factory-configured.
Three Factors Affecting Incubation Success
The original manual identifies three important factors that determine incubation results.
- The egg incubator
- The quality of the fertilized eggs
- The operator's care and experience
Healthy, fresh fertilized eggs and careful operation are essential for good results. The incubator alone cannot guarantee successful hatching.
Selecting and Storing Fertilized Eggs
- Do not use old eggs. The manual specifies a maximum storage period of 7 days, provided proper storage conditions are maintained.
- Never store fertilized eggs in a refrigerator.
- Store the eggs in a dark environment at approximately 18°C and 55% relative humidity.
- Before transferring eggs into the incubator, keep them for several hours at approximately 25°C to reduce temperature shock.
- Position eggs with their pointed ends facing downward.
- Do not wash the eggs. Clean them gently with a dry brush or toothbrush.
- Avoid eggs that are excessively large, excessively small or abnormally shaped.
Egg orientation: Position each egg in the automatic turning mechanism with its pointed end downward.
Egg quality: Poor-quality eggs or unsuitable storage conditions may reduce hatching results even when the incubator operates correctly.
Understanding the Incubation Process
The incubation process consists of two main stages: the Setter Stage and the Hatching Stage.
Setter Stage
During the setter stage, fertilized eggs remain in the automatic turning mechanism while the embryos develop inside the eggs.
For chicken eggs, the setter stage lasts approximately 18 days.
- Temperature stated in the incubation overview: 37.7°C.
- Relative humidity: 55–65%.
- Keep the eggs in the turning mechanism throughout the setter stage.
Hatching Stage
During the hatching stage, the developing chick no longer needs the egg to be turned.
The eggs are transferred from the turning mechanism to the hatching basket.
For chicken eggs, the manual describes a three-day hatching period.
Egg Candling — Days 7 and 14
Egg candling involves shining a light through an egg to examine fertility and embryo development.
The original manual instructs users to candle eggs on days 7 and 14.
Precautions During Egg Candling
- Perform candling in a dark room.
- Keep the room warm to avoid temperature shock to the embryos.
- Do not subject the eggs to strong shaking or sudden movement.
- Complete the procedure as quickly as practical.
- Remove transparent eggs showing no embryo development, as instructed in the manual.
Candling on Day 7
On the seventh day, developing eggs should show dark lines corresponding to blood vessels.
Candling on Day 14
On the fourteenth day, approximately two-thirds of the interior of a developing egg should appear dark.
If the entire egg remains transparent, the manual considers this an indication that no embryo has developed.
Infertile eggs: The manual instructs operators to remove transparent, infertile eggs to reduce the risk of contamination.
After the incubation cycle, the manual recommends examining eggs that did not hatch to identify the possible cause of failure.
It also states that eggs still containing unchanged yolk and egg white after 21 days were not fertilized. This statement is retained from the original manual.
Digital Household — Main Machine Components
1. PVC Body and Foam Insulation
The incubator body is made of PVC with a 3 cm foam insulation layer, according to the original manual.
2. Digital Temperature Controller
The incubator is equipped with a digital thermostat that has a resolution of 0.1°C.
Factory calibration: The controller is factory-configured. Do not change the settings unnecessarily.
3. Fan and Heating Element Assembly
The fan and heating element are mounted together in a dedicated holder.
The manual describes a heat-resistant silicone heating element.
The fan must operate continuously during incubation. Check its performance every day and make sure its speed has not decreased.
4. Egg Candler
The egg candler is used to examine eggs on the seventh and fourteenth days of incubation.
5. Automatic Egg Turner
The Digital Household incubator uses a motorized egg-turning mechanism.
The manual specifies three different types of egg cups for different bird species.
Instructions for changing the egg cups are provided in the accompanying instructional video.
Checking motor operation: The turning mechanism moves very slowly, so its movement may not be visible to the naked eye.
The manual advises checking for warmth and vibration at the motor to confirm that it is operating.
Motor connection: Make sure the motor plug is connected correctly and securely. A loose connection can prevent the turning mechanism from operating.
6. Multi-Channel Water Reservoir
The water reservoir contains several channels that can be filled to help control the internal humidity.
- Initially fill only the central channel with water.
- Wait approximately two hours and check whether the required humidity has been achieved.
- If the humidity remains insufficient, add water to another channel.
- Add water approximately every three days during normal operation.
Special filling container: The machine includes a container designed to help add water without removing the egg-turning mechanism.
Important: Begin with the central water channel. Do not automatically fill every channel before evaluating the humidity level.
7. Hatching Basket
The hatching basket is used only during the final three days of incubation for chicken eggs.
Do not leave the hatching basket over the water reservoir during the early days of incubation.
The original manual warns that doing so may prevent the humidity from rising to the required level.
During the hatching stage, remove the egg-turning mechanism, position the hatching basket over the water reservoir and arrange the eggs on the basket.
8. Humidity Gauge
The incubator includes a humidity gauge with the normal humidity range indicated in green.
Use this gauge to monitor the internal humidity during incubation.
Step-by-Step Installation and Startup
Follow the installation and startup procedure described in the original Digital Household manual.
- Position the water reservoir correctly inside the incubator.
- Add water to the central channel of the reservoir.
- Place the automatic egg-turning mechanism over the reservoir.

- Maintain the specified internal temperature of 37.5–37.7°C.
- Maintain the specified relative humidity of 55–65%.
- Perform egg candling on the seventh and fourteenth nights.
- Keep the ventilation openings unobstructed.
- Make sure the lid remains securely closed.
Hatching Procedure — Day 18 for Chicken Eggs
On the eighteenth day of chicken incubation, the eggs must be moved from the turning mechanism to the hatching basket.
- Remove the automatic egg-turning mechanism from the incubator.
- Add enough water to the reservoir so that opening the lid for refilling will not be necessary during the following days.
- Position the hatching basket over the water reservoir.
- Transfer the eggs gently onto the hatching basket without shaking them.
- Perform the transfer in a warm room to reduce the risk of thermal shock to the embryos.
- Close the incubator lid securely.
- Reconnect the machine to its electrical supply as described in the original manual.
- Avoid opening the lid during the final three days except in emergencies.
Hatching warning: Unnecessary opening of the incubator during hatching may disturb the internal environment and affect chicks still inside their eggs.
Removing Newly Hatched Chicks
The source manual describes opening the incubator on the second and fourth days of the hatching period to remove chicks.
Important source clarification: The same manual describes the chicken hatching stage as three days and instructs users not to open the lid during the final three days except under emergency conditions.
It also describes chick removal on the second and fourth hatching days. These statements are not fully consistent. Please confirm the appropriate timing with CocksMachine before relying on a precise door-opening schedule.
Humidity During Hatching
The original manual states that humidity may increase when chicks begin emerging from their eggs.
It describes this increase as normal.
Extended Hatching Period
The manual notes that some chicks may continue hatching until day 25.
Drying Newly Hatched Chicks
According to the original manual, chicks may remain inside the incubator for up to 48 hours while drying.
During this period, they use nutrients remaining in their yolk reserves.
Cleaning and Routine Maintenance
- Never use chemical cleaning products on the incubator, as instructed in the manual.
- Keep the water reservoir and filling channels in suitable working condition.
- Make sure the ventilation openings underneath the machine and on its lid remain clear.
- Check the fan every day during incubation.
