I checked on the babies again at 10AM and the 2 non-fosters were both out of the hut.  I think I-Pod may be pitching them out. She is also moving the hut and not always moving all the babies. The are eating, so as long as I stay on top of things (read stay home to be at their beck and call) and keep putting them back in the hut, everything should be ok.

It's a catch-22.  The more I disturb the nest, the more uneasy I-Pod becomes and the more she moves the hut.  But I have to check the babies and be sure they are in the hut and eating. So I-Pod gets upset and chucks them out, and the circle continues.  The joy of being a breeder.  *sigh*
