>>“FWIW I have 3 consecutive zero nosema tests
yet all my hives have ccd symptoms (now down to 16 + 12??)
At least in the late winter and early/cold spring, tracheal mites would cause a lot of bees to be weakened to the point where they will die in flight away from the hive. There will be brood and a queen left behind. Another possible scenario to consider.
