Unfortunately, it is not always possible to determine whether an egg is fertile or not without candling it, which involves shining a light through the shell to look for signs of development. If you are not comfortable candling the egg, it is best to err on the side of caution and assume that it is fertile.
2. Remove the egg from the nest.
Leaving a fertilized egg in the nest without a parent bird to care for it will likely result in the egg not hatching or the chick not surviving. Gently remove the egg from the nest and place it in a warm, humid incubator or brooder.
3. Incubate the egg.
The ideal incubation temperature for most pet bird eggs is between 37.5 and 38.5 degrees Celsius (100 and 102 degrees Fahrenheit). The humidity should be kept around 55%. You can use an incubator or brooder to create the ideal conditions for the egg.
4. Monitor the egg.
During incubation, it is important to monitor the egg regularly for signs of development. The egg will change in appearance as the embryo develops, and you will eventually be able to see the chick's eyes, beak, and wings forming. You can also candle the egg to check for signs of development.
5. Prepare for the chick to hatch.
When the chick is ready to hatch, it will pip the egg, which means it will make a small hole in the shell. This process can take several hours. Once the chick has fully emerged from the shell, it will need to be placed in a clean brooder with fresh food and water.
It is important to note that raising a pet bird from an egg can be a challenging and time-consuming process. It is important to do your research and make sure that you are prepared to care for the chick before you begin the incubation process.
