Bad luck Orpheus. Looks like they may have swarmed again.
but numerous sealed QCs in both colonies.
There's of course another reason why your bees might fail:
sublethal poisoning with systemic neonic pesticides.
If you are within foraging range of fields that have been planted with neonic treated seeds then your bees might bring home contaminated nectar and pollen from either the crop itself or plants growing in the verges.
If the contamination is quite low, you might not notice any direct toxic effects, but the colony could stop thriving and the queens might fail.
Early supercedure seems to have become a hallmark of areas with high rates of neonic treated oilseed rape: the bees bring in a lot of OSR honey, but soon after that the colonies stop developing and could even try to replace their queens.
If you have any chance, track down the farmer growing the stuff and investigate what he has planted, if you explain the problems you are having with your bees he might reconsider re. using those pesticides again.
There's another thread on this forum which mentions frequent supercedure, and I am a bit surprised that I am the only one pointing out a possible connection to systemic neonicotinoid pesticideds, mostly used on oilseed rape crops.

Two of my colonies have flummoxed me. They both swarmed in April despite swarm management techniques, they both developed new queens and up until three weeks ago were both laying and building up, then when I inspected them last Saturday both appear to be queenless, no brood seen, but numerous sealed QCs in both colonies. They had food, room to grow, they were only covering 6 to 7 of the 11 frames, both colonies had a super on. Seeing as the bees have more experience than me I've left them to it. Hopefully they'll develop new queens and build up again.
I wouldn't let any colony requeen itself if it produced more than half a dozen developed QCs in swarm preparation.
