our mistake with this hive was letting it get too big and having an outside feeder. A larger hive promotes angry bees, at least in our experience. An outside feeder attracted bees that did not belong in the hive, both robber bees and even aggressive, Africanized bees that are more likely to try to enter and take over your gentle hive.

Our solution with this hive was to take it apart and divide it. Then we introduced new gentle-stock queens to turn over the genetics of the hive (in about 30-45 days). Eventually, the hive returned to being a gentle hive.
