Golden Egg Incubator — Operation, Egg Preparation and Hatching Guide
Successful egg incubation requires suitable environmental conditions, healthy fertilized eggs and careful operation. Read this guide before starting an incubation cycle.
This page presents the general incubation instructions translated from the supplied manual. Product-specific specifications must be checked against the actual Golden model, because the supplied source document identifies the Twin model.
General Incubation Conditions
- Operate the incubator for one or two days before placing eggs inside to check that it works correctly.
- Start with inexpensive fertilized eggs if you have limited incubation experience.
- Do not install the incubator outdoors, in direct sunlight or where it is exposed to wind.
- Keep the machine away from direct hot or cold air produced by air-conditioning and heating systems.
- Do not operate it in a poorly ventilated space.
- Keep all ventilation openings unobstructed.
- Do not place the incubator on carpets or materials that could block the lower air inlets.
- Keep room-temperature fluctuations within the 4°C maximum specified in the source manual.
- Pay attention to daytime and nighttime temperature differences.
Ventilation warning: Do not block the air inlets or the ventilation opening on the incubator lid.
Three Factors Affecting Incubation Success
The original manual identifies three main factors affecting successful incubation:
- The egg incubator.
- The quality of the fertilized eggs.
- The experience and care of the operator.
Good equipment alone cannot compensate for unhealthy eggs or incorrect operating conditions.
Selecting and Storing Fertilized Eggs
- Do not use old eggs. The source recommends storing fertilized eggs for a maximum of 7 days under suitable conditions.
- Do not store fertilized eggs in a refrigerator.
- The recommended storage environment in the source is a dark place at 18°C and 55% relative humidity.
- Before placing eggs into the incubator, keep them for several hours in a warmer environment at approximately 25°C to reduce temperature shock.
- Place eggs with their pointed ends downward.
- Do not wash eggs. Clean them gently using a dry brush or toothbrush.
- Avoid excessively large, excessively small or abnormally shaped eggs.
Egg orientation: The pointed end of each egg should face downward when the egg is placed in an appropriate turning cup.
Understanding the Setter and Hatching Stages
Setter Stage
During the setter stage, the embryo develops inside the egg while the egg remains in the turning mechanism.
- Chicken setter stage: 18 days.
- Temperature specified in the source: 37.7°C.
- Relative humidity specified in the source: 55–65%.
- Eggs remain in the turning mechanism during this period.
Hatching Stage
During the hatching stage, the embryo is sufficiently developed and egg turning is no longer required. The eggs must be placed in the hatching basket.
- Chicken hatching stage: approximately 3 days.
- Remove the turning mechanism according to the appropriate instructions for your machine.
- Transfer the eggs gently to the hatching basket.
- Avoid sudden movements or temperature shock during transfer.
Important: Avoid opening the incubator during the final three days of chicken incubation, particularly after chicks begin hatching, except where intervention is necessary.
Egg Candling — Days 7 and 14
Egg candling uses light to check whether an embryo is developing inside the egg.
Safety Precautions for Candling
- Carry out candling in a dark room.
- Keep the room warm to reduce temperature shock.
- Avoid strong shaking or sudden movements.
- Complete candling in the shortest practical time.
- Identify transparent eggs with no visible development, as described in the source manual.
Day 7 — First Candling
Developing eggs should show blood vessels, which appear as dark lines inside the egg.
Day 14 — Second Candling
Approximately two-thirds of the inside of a developing egg should appear dark. The original manual describes fully transparent eggs as eggs in which no embryo has developed.
Unhatched eggs: After the incubation cycle, the manual recommends examining eggs that did not hatch to investigate possible causes.
Temperature Control and Factory Settings
The source manual states that the temperature-control system is configured at the factory.
Do not change factory settings unnecessarily. Incorrect adjustments can affect incubation performance.
For this Golden guide, model-specific controller-button combinations have deliberately not been copied from the Twin model.
Fan and Air Circulation
The ventilation fan must operate continuously during incubation. Check it daily and make sure its speed has not decreased.
- Keep air inlets and outlets unobstructed.
- Check for any reduction in fan speed.
- Avoid placing the incubator in an enclosed, unventilated space.
- Keep ventilation pathways clean before beginning a new incubation cycle.
Water Reservoir and Humidity Management
The supplied source describes a water reservoir with multiple channels. Because the source specifically identifies the Twin machine, this reservoir arrangement should not be assumed to be identical on every Golden model.
- Use the correct water-filling arrangement supplied with your Golden incubator.
- Monitor humidity throughout the incubation period.
- Do not block ventilation openings while trying to increase humidity.
- Check the water reservoir before beginning a new incubation cycle.
Model-specific confirmation: Do not use Twin-specific tray arrangements, motor connectors or water-reservoir instructions unless your Golden model has the same components.
General Startup Checklist
- Choose a well-ventilated indoor location.
- Check that the incubator is correctly assembled according to its actual model configuration.
- Confirm the ventilation openings are unobstructed.
- Inspect the fan and temperature-control system.
- Check the water reservoir and humidity indicator.
- Connect the incubator using its original approved power arrangement.
- Run the machine without eggs for one or two days.
- Check that internal temperature and humidity are stable.
- Prepare fresh fertilized eggs and position them correctly.
- Start the incubation cycle and schedule candling for days 7 and 14.
General Hatching Precautions
- Transfer chicken eggs for hatching at the end of the setter stage according to the correct equipment instructions.
- Use a warm environment during egg transfer.
- Avoid unnecessary opening of the incubator during hatching.
- Monitor temperature and humidity.
- The source notes that newly hatched chicks may remain inside the incubator for up to 48 hours while drying.
Source timing discrepancy: The supplied manual describes a three-day hatching period and advises keeping the door closed during that period. It also mentions opening the door on the second and fourth hatching days. These instructions conflict and must be clarified before establishing an exact chick-removal schedule.
Cleaning and Maintenance
- Check and clean ventilation openings between incubation cycles.
- Ensure that the fan works correctly.
- Inspect turning equipment appropriate to the Golden model.
- Inspect the water reservoir.
- Do not interfere with factory-calibrated electronic settings.
- The source manual advises against using chemical cleaning products.
- Check the machine before placing eggs for a new cycle.
Incubation Periods for Different Birds
The following values come from the incubation-period table in the supplied manual.
| Bird Species | Incubation Period |
|---|---|
| Chicken | 21 days |
| Peacock | 28 days |
| Ostrich | 42 days |
| Goose | 28–31 days |
| Swan | 30 days |
| Pigeon | 16–18 days |
| Pheasant | 20–24 days |
| Quail | 17–18 days |
| Partridge | 23–25 days |
Species-specific instructions: The 18-day setter and three-day hatching schedule above refers to chicken eggs. Other species require their appropriate incubation schedules.
