Tim, Nice To hear that it shows its Claws. No One Else has nursed your bees but you.
To handle big hives needs skills. Nothing such comes for free or by itself.
What is important To big hives that they get Foundations during flow To be drawn. It hinders swarning
It is important too that extract capped honey and return combs to the hive that bees have place where to store nectar. Empty Combs/foundations over brood.
When brood box has frames which are almost full of honey, move them up to be capped and hive Foundations or empty Combs instead the brood box. But do that after biggest riot.
When good flow is on, big hive is mere mesh. But when blooming is over, hive arranges nicely brood and nectar. It is best that nectar is in the hive and not any more on field.
