Today I put the feeders ontop of my hives. My feeders replace the crown board, so I will fill them tonight after the bees have settled for the night
I had a quick look in the hive that I thought was making swarm preparations 3 weeks ago. I found the queen, who was still laying eggs, although not many. I also found this queen cell from which a virgin queen had emerged from the round hole in the tip.
I now believe this hive had been planning on superseding their queen 3 weeks ago. Hopefully there are a few drones out there for this queen to get mated.
