It depends. If you only have a girl cockatiel and it has lay-ed an egg it obviously has nothing inside it cause it hasn't done anything so u can just chuck that sort of egg out, but if u have a male and female cockatiel the best idea is to get a little bowl thing or a nest sorta thing and put either cotton balls or tissues in there and then make sure there is enough room for Ur cockatiel to sit on it and then wait till it hatches and yaaaaayyyy!!!!! you have a baby bird.
about long as 2 weeks
It takes about 18-21 days for cockatiel eggs to hatch.
they are protecting their egg.
pick up the egg
If you can hatch a regular egg in there then you can hatch an ostrich egg.
Nothing is called a deoxys egg.. You can get one, only by cheating. Your egg is cheated, it most will never hatch, deoxys may hatch at from 0 to 30 000 steps. Good luck
you don't it just hatches. But, walking with the egg in your party will help it hatch
A pet cockatiel typically carries eggs for about 18 to 21 days before they hatch. The incubation period can vary slightly depending on factors such as temperature and humidity. During this time, both the female and, occasionally, the male may help keep the eggs warm. After hatching, the chicks will remain in the nest under parental care for several weeks.
* Can you make an unfertilized egg hatch? No
Not all cockatiel eggs necessarily hatch. Factors such as fertility, the health of the parents, and environmental conditions can influence hatching success. Typically, a clutch of eggs may contain some that are fertile and viable, while others may be infertile or fail to develop properly. It's common for pet owners to find that not every egg in a clutch hatches.
An un-fertilized egg will NOT hatch.
Well, it depends on if the cockatiel is willing to raise the egg that is obviously not it's egg. If it is, then the bluebird chick will learn how to live life as a cockatiel. The bluebird will never have a crest, but it will learn the cockatiel's language as it's own and think it is a cockatiel because that is the type of bird it is living with. However, if you had a wild cockatiel and you set a bluebird egg in with the other eggs, the cockatiel would reject the eggs because they do not look right or smell right, and would drop the egg out of the nest. I hope that answered your question. :) - Emily Sage
