My hives are doing well this year for first year hives, best I can tell. This hive has a single deep brood chamber with a queen excluder and two medium supers on top. In the honey supers I am using a mix of partially drawn comb from last year, new foundations and new foundationless frames from Walter Kelly alternated between frames with foundations. I was checking the honey supers yesterday and found that the bees have built up some of the foundationless frames with drone cells! I am only a second year bee keeper and don’t know if this is normal behavior. I have a green drone frame down below the excluder which is partially drawn and what is drawn is full of honey. I’m not complaining about the large drone cells in the supers as the huge cells look like they hold more honey than the “normal” cells, but I’m just a little surprised. And of course, should I worry about it? Is it a sign of something going on that I should/could fix?
