But, keep in mind, most ferals are not being feed syrup either which adds a lot of moisture to the hive.
Have to agree about the syrup.
But let me ask another question.
If we feed syrup only during Spring, Summer, and Fall, maximum ventilation is done on the hive in the warm conditions.
Then stop feeding near mid-Fall and close up all vents and insulate like a feral colony, would you think we will have moisture issues?
Guess there's another question that's similar to the above, when bees intake syrup and then turn it into honey placed into the cells, is the water value the same or higher than say natural nectar turned into honey? (If same, moisture level would be equal. If more, of course then the sugar syrup honey would create more moisture)
