I have a puzzle for you. A neighbor says she saw a huge swarm in our tree (2 separate cones of bees)for the majority of the day and then "the sky was black with bees". Sick at heart we looked in the hive today and it looks just as it did when we checked on Thursday. There were some queen cells (3 swarm based on the placement on lower part of frame)but we just left them alone and added a honey super. They still are drawing out the #1 and #10 frames on the 2nd brood frame. If they don't look like they've swarmed and they had ample room, did they really swarm. It seems too much of a coincidence to have a feral swarm in our tree in town. Our other hive has more bees (always has) but they are currently infected with a black, hairless virus. We gave them another honey super (total of 2) to be sure they have enough room. All input is appreciated.
