The eggs themselves do not change in size. If the mating was successful, you might have 2 baby cockatiels in the next several weeks. There might also be more eggs coming; a clutch of 2 eggs is kindof small.
no, they don't. Sometimes, the eggs can just be duds, and the bird just randomly popped it out. I've had that before, and it's a male. (both male and female birds can lay eggs) But, females always have the fertilized ones ...i think...

No, eggs are not meant to grow. They are meant to protect the growing chick inside.
