From Philip Chandler, the Barefoot Beekeeper, in the BioBees forums:

A good general principle with bees is – if in doubt, do nothing. More often than not, the bees are doing what needs to be done. The exceptions are almost always when they are trying to correct a situation created by a human.

BTW – sorry to correct you, Barbara, but a queen is three days in the egg, five as a larva and seven to eight sealed inside pupating, for a total of 15-16 days to emergence. She will usually mate 5-10 days after emergence, but it can be longer if the weather is unsuitable.
