I don't use queen excluders (aka honey excluders), but this may bring up a whole line of discussion. In our hives, the two deeps on the bottom are for brood and honey storage for the winter, the med. super above is to harvest if they fill it. For the winter in VA, they need 40-60 lbs of honey which they will make and store in the 2 deeps without difficulty. We have found however that they stop building comb by the beginning of July so if you don't have drawn comb already, you may not have a med super drawn and filled to harvest in the fall. Remember, they must have that 40-60 lb minimum to make it through the winter. Around here most people don't harvest honey in the first year unless they have exceptional polen and nectar sources, or an unusual hive.
