The bees tend to know what they need more than the beekeeper does. G3farms is correct, there is probably another Queen already. She will find a way to breed and start laying ASAP. Faster than you could provide another Queen, anyway. If there isn't another queen then you have Queen cells already. The bees are doing what they need to do.
I remember the first time I heard a newly hatched Queen piping. I had heard about it, and read about it here, but to hear it and realize what it was let me know that all was well in that hive.
