I have top bar hives. One threw off two small supersedure swarms over the past two weeks. I was able to catch the second tiny swarm. I have them in a hive with a heater and the queen is laying. It is a very small swarm that could not survive the winter. I was thinking of them in a small hive and raising them in a back bedroom I never use. They could fly around in the room. I would feed them syrup, pollen and candy and put them outdoors in April. Has anyone raised one indoors and any advice you can give me?
