The other day(Aug. 20, 2014) I think I saw a Queen leaving the hive. She was long and skinny. None of the other bees were paying any attention to her. The hive is a Warre' that I started early May. The hive has been very busy and by tapping on the boxes it sounds like 2 boxes are full. The third box doesn't sound as solid as the top two. The bottom box sound hollow. All summer the bees have been very gentle I could sit in a chair a couple feet from the entrance and the bees would just fly over my shoulder on their trips in and out. Last week I was stung so I moved the chair back to 6 ft. away. This morning I was stung again and was chased a short distance. Is the change in attitude plus seeing a maiden Queen leave a sign of overcrowding and a pending swarm?
