To incubate goose egg succesfully, you must maintain the proper environmental condition for the goose eggs to develop correct. To monitor the development of the goose egg, you can perform a process known as candling. Candling involve holding the goose egg up to a bright light in the dark to examine the development within the egg.
Because goose eggs has thicker shells than chicken eggs, you must use a high-powered LED candler to effectivey see through the shells of the goose eggs. During the first few day of incubation, the inside of the goose egg will appear clear because the embryo has not yet develop within the egg. By day five of incubation, you may be able to see faint vein that spread from the center of the eggshell.
How to Incubate and Candle Goose Eggs
If you are able to see these veins, it mean that the goose egg is fertile and that the embryo within the egg is developing. In order to assist the goose eggs in developing proper, you must maintain the proper temperature and humidity within the incubator. You must set the incubator to 99 degrees Fahrenheit to allow the embryo within the egg to develop without being harm by too much heat.
Additionally, the humidity within the incubator should be set to between 55 and 65 percent. However, prior to the lockdown period, the humidity should be increased to between 55 and 65 percent. During the incubation period, you must rotate the goose eggs three time each day to prevent the embryo from becoming stuck to the shell.
Additionally, you should mist the goose eggs with lukewarm water once per day starting on day seven of incubation. To mist the eggs, you must remove the eggs from the incubator for ten minutes, then spray the eggs with lukewarm water. After misting the eggs, return the eggs to the incubator.
Misting the goose eggs help to even out the moisture and temperature within the eggs. The air cells within the eggs are indicators of how the goose eggs are developing. Air cells are located at the large end of the egg and become larger as the gosling inside the egg consume the liquid within the eggshell.
If the air cell within the egg is too small, it indicate that the humidity within the incubator was too high, which could lead to the gosling becoming drowned in its shell fluid. If the air cell within the egg is too large, it indicates that the humidity within the incubator was too low, which could cause the membranes surrounding the gosling to stick to the shell. You should check air cells each week during the candling process to ensure that the air cell is grow at a steady rate.
Between day ten and day fourteen of incubation, the veins within the egg will continue to fill more of the egg. Additionally, by this time, you may be able to spot the embryo within the egg moving. If there is no movement within the egg, or if the inside of the egg have developed into a red circle within the incubator, known as a blood ring, you should remove that particular egg from the incubator.
You should remove problematic goose eggs from the incubator as soon as spotted to prevent the development of rotten eggs that may explode within the incubator. From day ten until day 23 of incubation, the inside of the egg will continue to darken until it appear nearly black when viewed through the incubator. The breed of the goose within the egg will determine the length of time that the embryo will take to hatch from the eggshell.
The Chinese goose variety take approximately 28 days to hatch from the eggshell. However, breeds of geese that is heavy in build can take up to 35 days to hatch. Because different breed of geese take different lengths of time to hatch from there eggs, you must adjust the incubation schedule to match the breed of the goose from which you are incubating the egg.
During the lockdown period, which last between day 26 and day 28 of incubation (depending on the breed of goose being incubated), you must stop turning the eggs. Additionally, you must increase the humidity within the incubator to 80 percent. When the gosling begins to hatch from the eggshell, you will spot an internal pip within the eggshell, which is the shadow of the goslings beak poking through the membrane that surrounds the embryo.
Following the hatching process, the gosling will perform an external pip, which is when the gosling use its beak to create a crack in the eggshell. It is normal for the gosling to hatch from the shell on its own; you should not aid in the gosling’s exit from the shell. The process of zipping out of the shell during the hatching process allow for the gosling to build its leg strength before it exit the shell.
Finally, once the goslings have exited the shell, they will dry in the humid incubator prior to being move into a brooder.
