Do you see any Queen cells in your hopes?
Before you run out and buy a Queen, you need to make SURE you don't have one.
They may be superseding her naturally or you could have had a swarm.
Takes 21 days for Queen to emerge, a few days for her to be able to fly, and a week after mated to get the egg laying process down, you can be 4 or 5 weeks before you see eggs from a newly mated Queen
