Local feral survivors in eight frame medium boxes.
I continue to use them.
It is too big for worker comb and too deep for drone comb. I have never had any brood raised in it.How does the flow hive fit into natural beekeeping? Is it small cell?
See above. I do not use an excluder.Also - unless one is using a queen excluder, how do you ensure no brood makes it into those cells?
I have not observed any of that. The bees fix the walls and fill them with honey. Like any super they only really work when there is a flow, but on a flow they fill them like any other fully drawn plastic comb...With the repeated need of the bees to repair the wax (after cracking the cells to drain honey) - don't the cells eventually thicken (I wouldn't see the bees being able to keep the walls as thin as a first drawing would be - they do not appear to do so elsewhere)?
