Yes. Your female cockatiel may lay an egg however without a male it will not be fertilised and therefore a dud.
FEMALE
A male finch can't really live with a female cockatiel as you should not mix straight-beaked and hooked-beak birds.
You cannot. A female cockatiel needs a male cockatiel to mate with her before she will produce fertile eggs. And incidentally, birds do not "fall pregnant".
Yes, that's how you get more cockatiels.
A female will lay eggs wether she has a male to fertilize them or not. These eggs will never hatch without the male. But with a male and female they will have intercourse where the male will fertilize the female and then after a few months the female will lay fertile eggs and a few more months they will hatch into baby geckos
A cocktail is an alcoholic beverage. There is no gender for it. A cockatiel is a bird which has a gender.
No, they fertilize it before they are layed
If the queen fertilizes the egg from her store of sperm, the resulting insect will be female. If she does not fertilize it, it will be male.
to fertilize the eggs
23 from the female and 23 from the male.
Well, they tried to anyhow. Probably. That's how they do it. if the male jumps on the females back they were trying but they got interupted by someone walking past them or coming to their cage.
