FEMALE
Yes. Your female cockatiel may lay an egg however without a male it will not be fertilised and therefore a dud.
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 cocktail is an alcoholic beverage. There is no gender for it. A cockatiel is a bird which has a gender.

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.
because they saw sadafs enormous face
if you want babies
the male gold finch is bright yellow with black and white wings the female is brown with black and white wings
Maybe. Cockatiels have personalities and chemistry just like humans. My male used to be a jerk to my female, but now they have a baby and constantly preen each other.
