I've noticed the last few weeks my hive has been getting weaker. Today I decided to to an inspection. I found empty cells! No eggs, no or few capped brood cells. The bottom hive body was void of any eggs, or brood. There was very little honey and a little pollen. My second brood box has some uncapped honey and pollen stored. Should I combine this hive with another of my hives or add a few frames of capped brood from another hive? It's getting kind of late in the year and I don't know if there will be enough time for them to make their own queen and make brood and still survive the winter. What should I do?
