The colony survives the winter and I can add a couple of honey supers to the bottom box. Supers can be a different size than bottom/brood box. I use honey supers that are about half the size of the main box. This makes it easier to lift the supers and add additional supers as needed. The bottom box is mainly used for the four states of bees, egg, larva, pupa, & adult. When a hive is inspected the bottom/brood box should have all four stages.
