Okay, so here's what I did. My sister made a makeshift queen marking cage using 2 cups, one on top of the other; she copied it off a guy on YouTube. We used silver Testors model paint, since that was the most visible color we had, and we tested the marking cage on a couple of drones and on a queen that we'd pulled from the hive yesterday who had a damaged wing and couldn't fly. Then we went into the hive to try and find the two queens we left in there yesterday and any more that may have hatched. We went through the whole hive, checked each frame, and removed all the queen cells that were still capped. We found only one queen in the hive, and put her in a jar so we didn't lose her again. My sister and I were talking about whether or not we could have missed a queen somewhere in the hive, and I peeked around the front of the hive to see if there were any dead queens on the ground, thinking maybe they had in fact fought it out overnight, and there was a live queen sitting on the landing board! I don't know if she was in the bottom box and crawled out due to the commotion from the inspection, or maybe she was coming back from a mating flight. On the off chance she was mated we picked her to be the winner, and we caught her and marked her, and put her in the hive. We removed the other queen we had found earlier. This means we found both the queens we'd left in there yesterday. So I came back inside and watched the end of the NASCAR race, and then I went back outside to clean up. I went back up to the hives and the bees had something balled on the landing board. So I brushed the workers aside and inside the ball is another queen! She's not the one we marked, and the bees seemed to be attacking her. I got her in a cage and she seemed like she was pretty far gone, so I stuck her in the freezer. Does the aggressive behavior toward this queen indicate that they've accepted the marked queen?
