atiels Problem, please help..?

It is normal for the Male bird to try to take care of the Eggs himself. Our Quaker Parrots and Parakeets do the same thing. The Female usually Lays the eggs and the Male Protects them. The Female is sapossed to bring back food to the Male, Its probably there first time Mateing and not knowing what to do. I would say though to keep her with the eggs if your going to seperate them, beacuse once they hatch, shes going to need to be there to feed them, and when they hatch you dont want to put the male back just yet because he might kill the babys, not remembering that they are his.
