Well, just bought a breeding box for the ****atiels, there are currently 2 eggs on the bottom of the cage. I know they aren't viable, and will remove them soon. BUT!

How do I best care for the birds and their eggs? Do I just leave them alone, but make sure they have lots of food, seed, fruit & veg and water? Or is there anything else I should do? do I open up the lid of the box to look in? Help!
