After requeening two hives (my first attempt at this), I left them alone for a week, then went in this morning to check and see if the new queens had been released from their cages. The first hive was just fine; the queen was released, and I could even see the her wandering about on a frame.
The second queen had also been released, but there were four large queen cells hanging from the bottom of one of the frames, and I'm pretty sure there were others. These cells weren't capped, but looked pretty advanced. There were no queen cells in the hive prior to requeening.
Is this a good indication that the second queen wasn't accepted? If so, will they have time to raise their own queen this fall?
