The history is. I set up my KTBH this spring with a feral swarm from Lisbon OH. They were doing very well and drawing comb without much interference from me. Queen was laying well and so forth. Last week I decided to put some syrup into them. While poking around I noticed a swarm cell on the last drawn frame from the entrance. I decided to think about what to do about it for a day and forgot altogether. I opend the hive yesterday and the cell was still capped and I saw larva so I cut the cell out. Now they were a little more agressive than my others but that might have been the weather. I disected the swarm cell and found a fully formed (dead) queen. I went to squish her and she was empty, no gooey filling. What gives? Do I have a disease? Help please. Thanks.
