village: NOO!!! you're nOT supposed to clean the nesting box until the babies are at least a week old! But some of the old nesting material back in there...anything really with their scent in it. Just leave them alone, and in a quiet place, even cover the cage like on 3 sides. Hopefully they'll go back in. =]
yang: nope! The parents will feed them all by themselves. Read my breeding post. I say a little more about it in there.
mtlj's mom: you don't need the eggshell (i've never used it.) as long as you have a powder calcium supplement. =] and i know you have that.
