Hi Ed @Red_Hot_Chilipepper
I had a strong hive so I split it to help stop it swarming on the 1st October.
I put the old queen in a hive in a new spot and the hive in the original spot made 14 queen cells starting around the 1st October.
The hive in the old spot then swarmed on the 18th October and I caught the swarm and put it in a new box. So the original hive is now three if you follow.
The swarmed hive failed to produce a laying queen as did the split in the original spot (I saw virgin queens in both hives on the 18th) , and both have been given frames of eggs and larvae each week for two weeks. Neither hive has made any queen cells.
I combined the swarm hive back with the original queen using newspaper. This was a mistake I believe as the unmated dud queen now might have killed the good old queen (probably 3 or 4 years old).
The split in the original spot is the one I am trying to now find the unmated queen in. I am about to go and split that in two and try adding brood again, assuming one has the dud queen and one does not.
There was bad weather here right when I would have expected the queens to go on mating flights.
