1. Age of the Cockatiel:
Cockatiels do not become sexually mature and fertile enough to produce viable eggs until they are around 18 months old, although individual cockatiels can vary. Trying to breed them before they are of age can result in infertile eggs.
2. Male Fertility:
The male cockatiel must fertilize the female's eggs in order for them to develop into chicks. If the male is not fertile or is unable to mate effectively, the eggs will not hatch.
3. Incubation Issues:
After the eggs are laid, the female cockatiel needs to incubate them at the proper temperature and humidity in order for them to develop properly. If the eggs are not incubated properly, they will not hatch.
4. Eggs Not Fertilized:
The male and female cockatiel must successfully mate for the eggs to become fertilized. Ensure the male and female cockatiels have bonded to increase their chances of mating and producing fertile eggs.
5. Lack of Calcium:
Calcium is essential for healthy eggshell development. If the female cockatiel is not getting enough calcium, the eggshells may be too thin or weak and the chicks will not be able to pip out of the eggs.
6. Environmental Conditions:
The nesting environment should be dark, quiet, and undisturbed to minimize stress on the female and her eggs. Sudden changes in temperature or humidity can also affect egg viability.
7. Cockatiels Age:
Older cockatiels may produce infertile eggs or eggs with reduced hatchability. The peak reproductive years of cockatiels are usually between 3-6 years of age.
If you are still experiencing problems with your cockatiel's eggs not hatching after trying to ensure proper conditions and calcium intake, it may be advisable to consult with an avian veterinarian for further evaluation.
