What would be the best way to combine a very weak top bar hive with a stronger top bar hive. I know how to combine Lang type hives together, but not sure about KTBH's. The weaker hive has a queen (I saw her) but I'm almost certain something is wrong with her, she was a new queen this spring with package bees. She began laying nice solid worker pattern for about a month, then my latest inspection the other day revealed no eggs or larvae, and lots of sealed drone brood, and just a handful of sealed worker brood. The hive population seemed to me to be declining for the last couple weeks with lots of drone bees on the combs. Need some quick help on this one please. Thanks.
