Parrot eggs take between 2.5 and 4 weeks to hatch, depending on the species. In general, the larger the bird, the longer the incubation. Egg clutches vary from two to six, and the hen bird lays one egg a day.
Incubators for egg-hatching are not essential kit for a breeder, but many still use them. The eggs of all parrots require a temperature of between 98F and 99F. Getting this right is essential for successful hatching.
A nesting Cockatiel needs leaving in peace to get on with the job
If an egg fails to hatch, there are many possible reasons.
- Females sometimes lay eggs when there are no males to fertilise them
- A female may lay unfertilised eggs if the male has failed to achieve a successful coupling
- Single eggs may fail to hatch, due to a chick failing to develop properly inside, or because the egg itself somehow managed to avoid being fertilised
- The hen may neglect her eggs due to inexperience or stress - this is quite common in first-time layers
- If the nestbox isn’t a suitable size and shape the egg may have fallen to the floor and killed the embryo inside
- The male bird could be infertile
- The proximity of other birds or external distractions may be the issue - the female may be too stressed to sit on her eggs
- Nutrition is important - if eggs fail to hatch due to soft shells, it’s a sign that the hen didn’t get enough calcium (from cuttlefish bone or a mineral block, for example) when she was producing the eggs.
