My budgie is in a breeding cabnit right now and she had 1 egg the next two days she had egg number 2 and then 3 days later she had egg number 3 and it is tiny i am sorry i cant put pics on but i cant find my lead.

 

will the egg hatch it is about 3 puaters the sive as a normal egg or smaller

some eggs are smaller than others so I would just wait and see.
