07-13-2013: Since I had skipped the top honey super (and I don't use queen excluders), I thought maybe the queen had gone back into the top box and I just didn't look there. So, a few days later, I took a queen peek in the top box. Honey, honey and more honey. Dang, now what? Could I have skipped a frame or two during my inspection and missed the brood? That doesn't seem to make sense since that would be a very small area to have brood only on a few frames. I saw no queen cells, so I don't think they swarmed. The proportion of workers to drones seemed right, so the hive hasn't become a laying worker hive.......yet. The last inspection where I spotted brood was on June 4th, so it has been more than 21 days, so the queen could have died and all the existing brood hatched out already. By all my logic, it seems that they are now queenless and my only hope of saving them is to order a new queen. Hopefully there is someone selling them this late in the year!
