Re: REMOVING HONEY SUPERS
That's typical late in the season when the queen slows down egg laying and the colony is preparing for winter. Make sure that you actually are in that mode and the fall flow is winding down. Crowded hives "will" swarm in September if the queen is still laying and she runs out of brood cells because too much is backfilled with nectar.

The new queens never had a chance to get out for mating flights. I figured it out too late.
To everything there is a season....
