I have a hive I can not figure out. Last week it swarmed. They started out as a normal swarm (a cloud of bees in the air) but ended up in two separate clusters. One cluster was under the hive on a 2x4. I have my hives on an elevated “bee bench”. The other cluster was 6 inches from the entrance of the hive on my garden fence. Within an hour or two both clusters had gone back into the hive. I did a hive inspection and found 5 sealed swarm cells. The hive is rocking and rolling with bees and brood so I could not find the marked queen. Monday, 6/2, they swarmed again. This time they (about 5lbs of bees) clustered on a crab apple branch about 25’ from the hive. A picture perfect swarm cluster. Within 50 minutes all but 15-20 bees went back into the hive. The 15-20 bees formed a “cluster” around the old queen, 6 inches from the hive entrance. I inspected the hive and found a swarm cell that a queen had emerged from but the other four cells had not been chewed into and the queens killed. I put the “old” queen in a queen cage with three nurse bees and put her in a hive that I have been working on to queen. Any thoughts?
