I have two weak queenless hives. I was going to put some frames of brood and eggs in. Can I leave the bees on frames or add bees from another hive. Is there any type of process in this or just swap them? I just pulled both hives both had just swarmed and no queen to be found. not many bees in eather hive. one is from a tree other from side of house. both had what looks like just hatched queen cells.
