I inspected my two top bar hives this afternoon.
I am still concerned about Metpropolis and am tempted to simply requeen it. The queen is alive and laying but the brood pattern is really spotty, possibly indicating an inbred queen. I will give it a week or two more.
Plan Bee... is booming with bees, larvae and eggs. I was unable to spot the queen but I did find one supersedure cell. I am not that concerned about this hive. It looks healthy and active. I might split it in the near future.
