I had a hive that started winter with fully capped cells but by spring, you
could shake the honey from the combs, as if it had never cured. The bees
suffered greatly. I was told that honey made from honeydew does exactly
what this honey did, ferments easily, even after curing. It is terrible for
overwintering bees.
So could it be the honey that is the problem, and not uncapped honey?
