Back in August there were so many bees in my hive that I thought they might swarm. They had built comb out to the center point of the hive so I took out the divider board and opened up the whole hive to give them more room. For a few weeks they kept building in the center of the hive but this weekend it appears that a lot of them jumped to the far end and started building comb down there leaving a bunch of empty bars in between. Maybe they're just being optimistic. Has anyone ever seen this in a top bar hive?
