Perhaps I've mentioned that we had two bee swarms recently. Both came from the hive on the far left, the Langstroth hive. The queen in that hive must be a baby-bee-laying machine!
After we draw most of the honey from the wax, we scoop the remains out and return it to the bees. I spread it out in a box on top of the hive. They will take every drop of honey in there, and much of the wax, and reuse it in the hive. Bees are extremely efficient creatures.
So ... now we have four hives! Two are fairly small. That Langstroth hive, if it continues to go strong, might welcome yet another split. We'll see.
