they are queenless, without any eggs, larva, or capped brood.
evidently that is the sound the queen in the supercedure cell makes before she hatches.
should i just cut my losses and combine this hive with the other new one?
Is it too late to expect them to build up enough population and honey stores to survive a Michigan winter?
If all brood are all hatched, it is not possible that there can be unhatched queen.
Development of queen is 14 day from egg and the worker is 21 day.
Also ordinary worker may give a "piip" sound like a gueen. But usually there is a new queen which not yet lay eggs.
In Finland it is now early summer. Bees have not collected anything. Colony needs 1,5 months to get ready for winter.
But it is summer and flowers in Mighican, you get honey if you put the colony together with another one. The rest of swarmed colony is very unable to collect honey.
When you go to your hive there may be a youg fat lady laying eggs.
