Left the supercede cells on - two in hives 2 and 3 but 4/3 weeks ago now. Possibly one turned drone laying (hive 2) and the other still waiting or lost on mating flight?? - will take your advice - and hope to end up with one good hive.
I have three hives that have been good for three years.
This year hive 1 appeared to have swarmed in mid April. So I put brood from hive 2 into it.
Hives 2 and 3 both had Qcells which we removed and seemed health.
Both appeared to requeen - just a couple of supersede cells. No numerous swarm...
Drone laying Queen
Sort of related - I seem to have a drone laying queen - if I buy a new queen will the bees rid the hive of the drone layer or do I have to find the queen and remove her myself first.
