Pictures, as promised, from my last inspection, when I released the queens.
I left the queens in their cages for a week, plenty of time for the bees to dig the new queen. Here she is in her cage, with a lot of happy bees feeding and grooming her through the wire mesh:
Here is a picture of spotty brood pattern. Ideally, in this picture the frame should be covered in capped brood cells. As you can see, much of the brood has been removed. The bees will remove any brood they think is diseased or unhealthy, which results in the spotty brood pattern.
In the picture, I am squishing an emergency queen cell.
In order to fit the queen cages into the hives, I had to remove a frame. In this picture, you can see where the bees are already taking advantage of the extra space to build more comb.
