they are protecting their egg.
pick up the egg
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
No the cockatiel should not be seperated from his or her mate after eggs have been laid. This should only occur if the male is aggressive to live and viable eggs. Visit cockatiel cottage for more info.
Yes. Your female cockatiel may lay an egg however without a male it will not be fertilised and therefore a dud.
remove her from the cage then remove egg
about long as 2 weeks
It takes about 18-21 days for cockatiel eggs to hatch.
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.
86% of the time a cockatiel's eggs aren't fertile. The cockatiel lays them if it is in love with you. If it lays them you have a problem, and it's called being egg bound. If an egg gets stuck, then your beloved bird will die.
No, only female birds lay eggs. If your cockatiel laid an egg, it's a girl!
If there was chirping in the egg, the bird was alive but not able to break the shell. No chirping today probably means it is no longer alive. Tap a hole in the egg and see if it continues the process.
