Second Queen Cell Still Intact - Why?

The second queen cell had not yet hatched as of yesterday afternoon and that queen would be 18 days old as of then. No sighting of the first queen but you would think that she would have destroyed any other queen cells in the hive.

Nearly all the dead bees that were on the bottom screen were now cleared away. Things seem well in the hive... but where is she? She will not beging to lay eggs until at least the 11th of April but I would sure feel better knowing she's around.
