I have two top bar hives.
What I was considering the stronger of the two has enough honey stores and some open brood (eggs and larva) but a bad case of mites. The weaker one has little honey stores closed brood and no visible signs of disease or mites.
At this point what is my best option for the upcoming winter? Should I treat the stronger one with the open brood even though it's late in the season? Should I combine them? Should I sacrifice the weaker hive and throw its capped brood in with the stronger hive?
