When I did my springtime inspection I discovered brood comb had been built between the bottom and top deep. I removed each frame,cleaned them and replaced them in the same sequence.
Yesterday I inspected the hives a found a couple had honey comb built between the bottom and top deep. The bees have plenty of expansion room in these hives. Does this comb building between deeps happen frequently? It just seems a pity to have to break up this comb when I inspect.
Any advice/info would be appreciated.
