So I let them move in. I did a brief inspection after a week and saw they were clustered and busy building combs.
After two weeks I saw they had capped cells. We looked over all the bees and there was no sign of a queen. All the capped cells were bullet shaped drone cells.
I figured it was a laying worker and that the swarm may possibly have originally come from Hive #2 which did go queenless and ended up with a laying worker.
The other day that's what I did. When I shook the bees most of them went up in the air. I then removed the equipment leaving them no home.
They began to gather on the platform where their hive was and several workers started to do home scenting. I felt bad for them.
Where on earth did she come from?
Then I realized that I had just shaken them out of their home. So I quickly put everything back together. The queen jumped on my hive tool and I set her in the hive.
Then all her workers marched inside while I stood there apologizing for the rude interruption to their day.
