I split a strong hive on June 5 because it looked like it was going to swarm. The queenless hive has yet to produce a laying queen. I have added a frame of eggs, larvae, and brood twice. The queen right hive is weak. The hive has 2 deeps, but the bees haven't expanded into the top box at all. My thought at this point is that I would combine the 2 hives back into 1. How would I go about this?
