I have one really healthy hive. One hive starting from a small swarm that I added two frames of brood and bees. My third hive has been dwindling. Loooking in it yesterday, there is a queen and she is laying but there is a lot of open comb and few eggs. The hive did FILL two deeps now the top deep is empty and there is not that many in the bottom one.
Should I requeen.
Can you supplement with bees from the other healthy hive without them robbing and going back home?
Should I kill the queen and combine the swarm hive with the weak one? (havent checked the swarm hive yet to see if that queen is laying).
I also noticed a lot of worms in the portions of a couple of frames. Hive beetle larvae?
