This season I have 5 queens. From a nuc in May the hive has swarmed in June and from then I have had swarm cells , supercedure cells and now emergency cells. I have managed to get enough eggs out off each queen to sustain the colony throughout the season. However I now find myself after having to introduce a new mated queen over a week ago the hive is again queen less and with no brood, eggs or larvae. Although the colony is very calm if will not survive the winter. I have an option to merge the hive with a poly nuc with a good queen which is situated only a few feet away. But really wondered if I should. Does anybody know if the hive itself may cause these problems. Currently the brood frames are currently being filled with nectar and pollen!
