Recently, I needed to add a super to my hives, to give them extra space for the spring that's happening now in Australia. Each hive was a little different, but they were all quite overdue for an extra super and was running out of space. I thought they would swarm possibly, but there wasn't much actual bees in the hives and I couldn't find any queen cells.
One hive was a single deep, it had a detachable base. Instead of adding a super on top, I decided to lift the whole thing off the base, and add a super underneath. I did this because the super was quite full of honey, and I figured I'd be creating more space for laying brood by placing the empty super where the queen prefers to lay, on the bottom super. Was this a mistake, or is this a good practice?
Another hive I had didn't have a detachable base. It only had two deep supers together, which were both quite full, especially the super on top was full of honey. I only had a manley sized super to add, so I decided to put the empty manley super between the bottom, and top super. The practice seems to usually be add the manley on top, deeps to have as brood chambers down below, but if I was adding a super to expand the brood chamber, to keep the queen laying and mitigate chances of swaming, did I do the right thing?
