Goose eggs are typically harder to hatch than chicken eggs, but with careful handling, anyone can achieve a great hatch rate. The incubation period for goose eggs is 29-31 days, but this can vary depending on the breed and environmental conditions. During incubation, the eggs should be turned regularly, either manually or with an auto-turner, to ensure robust goslings. Candling is a process used to check the fertility of eggs, and for goose eggs, it is recommended to candle around day 10 of incubation. By this time, you should be able to see veins and some movement inside the egg. However, some people recommend waiting until day 14 to be extra sure. During candling, you should look for solid darkness and a large air sac, avoiding eggs with a 'sloshy' appearance as these may have failed along the way.

When to candle goose eggs for the first time
Candling goose eggs for the first time requires patience and finesse. The process is more complex than with chicken eggs, but it can be very rewarding. The ideal time to candle goose eggs for the first time is between days 5 and 10 of the incubation period. During this period, it is important to monitor the eggs closely and maintain stable conditions.
Goose eggs typically have an incubation period of 28 to 31 days, with some variation depending on breed and environmental conditions. The first candling should occur relatively early in this process, ideally around day 10. However, some sources suggest that candling can begin as early as day 5 or 6, as this is when the early embryo is most fragile, and any issues with incubation can result in embryonic death.
When candling for the first time, there are several key things to look for. Firstly, the eggs should be solidly dark, with a larger air sac than when they were first placed in the incubator. You may also see the development of veins and possibly some movement. It is important to ensure that the eggs do not have a ""sloshy" appearance, as this indicates that the embryo has quit developing and the egg should be removed.
To ensure optimal conditions for candling, it is recommended to turn the eggs regularly during incubation. This can be done manually or with an auto-turner. If turning by hand, it is best to leave the eggs undisturbed for the first two days, and then turn them at least 3-5 times per day by 180 degrees. Marking one side of each egg can help keep track of their orientation. Maintaining proper humidity and temperature is also crucial for successful hatching.
By following these guidelines and closely observing the development of the goose eggs during the first candling, you can increase the chances of a successful hatch and experience the joy of raising healthy goslings.

How to identify if a goose egg is fertile
Goose eggs typically take 28 to 31 days to hatch, so candling them around day 10 is a good time to check for fertility. At this stage, you should see veins and perhaps some movement.
To identify if a goose egg is fertile, you can candle the egg by shining a bright light through it. A fertile egg will have a dark, solid mass, and you may be able to see veins and movement. If you are unsure, you can compare it to a store-bought chicken egg by shining a light through that. If the goose egg looks similar, it is likely infertile.
It is important to note that goose eggs should not be removed from the goose's nest, as mother geese can be very defensive and cause injury. If you do choose to remove the eggs, it is recommended to wear gloves and have assistance.
Additionally, the incubation process for goose eggs requires regular turning of the eggs. This can be done by hand or with an auto-turner. If turning by hand, mark one side of each egg and leave them undisturbed for the first two days. Then, turn the eggs at least 3-5 times per day, turning them a full 180 degrees each time.
The optimal relative humidity and temperature for goose egg incubation vary throughout the incubation period. Days 1-4 require a relative humidity of 63% and a temperature of 31.1°C. Days 5-12 need 54% humidity and 29.5°C, while days 13-23 require a slight increase in humidity to 56% but the same temperature. For days 24-27, the humidity should be 57%, and the temperature remains at 29.5°C. During hatching, the humidity should be increased to 77-80% with a wet bulb temperature of 33-34°C.

How to identify if a goose egg is dead or non-viable
Goose eggs typically take 28-31 days to hatch, though this can vary. It is recommended to candle goose eggs around day 10. By this time, you should be able to see veins and possibly some movement. If you candle the egg and it appears "sloshy", with loose and muddy contents, it has likely failed and should be removed.
To identify if a goose egg is dead or non-viable, you can candle the egg by shining a bright light through it to illuminate its contents. If the egg is fertile, you should be able to see veins and possibly some movement by day 10. If the egg is infertile, it will contain a bright white spot, 1-2mm across, called the germinal disc. A fertilised egg, on the other hand, will have a paler, larger circle with a pale yellow centre, measuring 3-4mm across.
If you are unable to observe any movement or veins by day 10, this could be a sign that the egg is non-viable. However, it is recommended to wait until at least day 14 before removing infertile eggs, as it is possible for veins to become visible later. Additionally, breaking open an unhatched egg can provide valuable information. If the egg was infertile, the contents will be entirely yellow, with no signs of an embryo or blood.
Another way to assess the viability of a goose egg is through listening and feeling for movement. If you can hear the baby goose peeping loudly and feel movement through the shell, it is likely viable. However, if there is no sound or movement, it may be a sign that the embryo has died.
It is important to note that the incubation process plays a crucial role in the viability of goose eggs. Proper turning of the eggs, maintaining ideal temperatures, and avoiding temperature shocks are all essential factors in successful hatching.

How to care for goose eggs before candling
Caring for goose eggs before candling requires several steps to ensure the eggs are viable and healthy. Here is a detailed guide on how to care for goose eggs before candling:
Incubation
Incubation is a critical step in the process of hatching goose eggs. The incubation period for goose eggs typically ranges from 28 to 31 days, with some variations depending on the breed and environmental conditions. During incubation, it is essential to maintain optimal temperature and humidity levels. The eggs should be placed in an incubator, which can help regulate these conditions.
Turning the Eggs
Turning the eggs regularly during incubation is crucial for the embryo's development. If using an auto-turner, ensure it is specifically designed to handle goose eggs. Alternatively, you can turn the eggs manually by marking one side of each egg and turning them at least 3-5 times per day, leaving them undisturbed for the first two days. Each turn should be a full 180 degrees, ensuring that the marked side is alternately facing up and down.
Cleaning the Eggs
Before placing the eggs in the incubator, they should be cleaned to reduce the risk of bacterial infection. Dirty eggs or an unsterilized incubator can introduce bacteria, leading to embryo deaths.
Candling Before Incubation
It is recommended to candle goose eggs before setting them for incubation. Candling involves shining a bright light into the egg to inspect its contents. By candling beforehand, you can identify cracks that might allow bacteria to enter during incubation. Cracked eggs are more susceptible to infection, which can cause premature embryo death.
Misting the Eggs
Light misting of the eggs with lukewarm water once a day is beneficial. This helps maintain the necessary moisture levels for the developing embryos.
By following these steps before candling, you can create optimal conditions for the goose eggs' development and increase the chances of successful hatching. Remember that careful handling, proper incubation conditions, and regular care are essential for the healthy growth of the embryos.

How to care for goose eggs after candling
Goose eggs typically take 28 to 31 days to hatch, which is longer than the 21 days it takes for chicken eggs. After candling, here are some steps to ensure the successful hatching of your goose eggs:
Turning the Eggs
Goose eggs need to be turned regularly while incubating. If you have an auto-turner, it is safe to turn on the machine and let it start turning the eggs immediately. If you are turning the eggs manually, it is best to leave the eggs undisturbed for the first two days. Then, start turning the eggs at least 3-5 times a day. Turn the eggs a full 180 degrees each time, making sure to mark one side of the egg to keep track of your turns.
Misting the Eggs
Lightly mist the eggs with lukewarm water once a day.
Lockdown
As you get closer to the hatching date, you will need to adjust the incubator settings. This process is called "lockdown". During lockdown, adjust the heat and humidity settings, ensure all air vents are fully open, and leave the lid on the incubator to maintain a steady humidity level. You will also need to stop cooling and misting the eggs.
Embryo Development
If you are candling around day 10, you should see veins and possibly some movement. If you candle earlier, around day 7, you should see a dark spot with spider-like veins stretching out around it. If you do not see this, do not worry; it can sometimes take until day 14 to see these signs of development.
Identifying Infertile Eggs
If you see a sloshy" appearance in the egg, with the contents loose and muddy, this is a sign that the egg is infertile and should be removed before lockdown.
