All right, it's done. It took long, several hours, but it went really well. Vacuuming at the entrance worked great and got the meanest bees out of the picture right away and before they even had time to alert the rest of the hive. Once bees stopped coming to the entrances to attack the vacuum, I cracked the lid and we vacuumed up everyone on the top bars. There weren't many foragers in the top, and there was also BIAS in there, so we looked for the queen, found her, and sent her on her merry way. The nurse bees up there weren't any hassle, so we set those boxes aside and then working frame by frame, we vacuumed up most of the bees in the bottom section of the hive. The bees down there were almost all foragers, and were pretty nasty, but the vacuum was quite efficient. The hive next door became a little bothered by the vacuum noise, so we did take a little break for about 15 minutes just so they could calm down, but other than that, everything was very safe and smooth and no one got stung. I left them with most of the capped brood that had been in the bottom of the hive, since there weren't any eggs or larvae of queen-rearing age down there (I removed any QCs they had made as we went). I made sure they had several frames of honey since they won't have many foragers for a while. The rest of the brood I put in the freezer. I'll uncap it and feed it to the chickens. We got 5 or 6 frames of capped honey out of the deal for ourselves, and the rest of the uncapped honey I'll spread around the yard for the other bees to cap. Thanks to everyone who helped out with this.
