I am a treatment free beekeeper with 7 years experience. I caught a small swarm my first year of beekeeping. This swarm has managed to survive mites, small hive beetles and my learning curve. I have purchased several other packages and they have all died out within 1-2 years. The problem with the survivor hive is that they are meaner than a 'junkyard dog'. I have split the hive twice. Both splits are also survivors but hot! I hate to kill the 3 queens. Does anyone know if I continue to split the hives will I eventually end up with a more gentle hive. Is temperament determined only by the queen? Can local drones influence the temperament and calm down the meanness? I would appreciate any suggestions. I want to save the survivor genetics but it is no fun to work these bees.
