I'm a first-year beekeeper, and have a few issues/concerns at this point. I started my hive in May. About 5-6 weeks ago, I added a second hive body to the first, as it seemed crowded, and was 75-80% full. The week after that, I did not see them moving up into the upper hive body, so I re-installed the hive-top feeder (maybe not the best idea, in retrospect). A week later, they had taken all the syrup, and stored it in the hive, filling it up, with no room for eggs. I saw the queen, and a few eggs, lots of capped brood, and lots and lots of stored syrup. I removed the feeder at this point. A week after that, I saw swarm cells all over the hive (queen cells along the bottom-those are swarm cells, correct?). Still saw the original queen, eggs and a few uncapped larvae along with a bunch of capped larvae. Well, again, I went back in a week, and there's at least 1/3rd fewer bees, no queen, and no eggs (just larvae and capped queen cells). I went to the hive yesterday, and they were busily flying in and out, bringing in all kinds of pollen. There were a few bees, however, on the ground in the front of the hive. Upon further inspection, I found them to be drones, which could not seem to fly, each of which had a few workers surrounding it. I picked up a drone to get a closer look, and was promptly stung by one of the workers. bah. I'm worried now...should I be? Any advice is welcome and appreciated! Thanks in advance! :-\
