I think Spike's egg was either dead or unfertilized, and that's why they let Celestia have it. The purpose of the test was to see how student's deal with failure, not to actually hatch the egg. Twilight's magic was so powerful that she either brought Spike back to life or fertilized the egg (which would mean that she is Spike's father!) and that's why Celestia took an interest in her.
