My first year with top bar hive has been educational but not too promising.
I have earlier lost queen and despite three queen cells, did not naturally replace queen. As population deminished, and drones took over, I successfully replaced queen and don't know if I have enough workers to get numbers up for weak hive to survive. Anyway, I took unused bars out to reduce risk of damage (moth or shb), and wondered what to do with drone cells. Will they modify upon needs or should I just cut out foundation and let them completely rebuild? Going to feed but doubt they will desire to make brood as cool temps and nectar flow waning. Wish us luck
