Honey is definitely responsible for most of the hard work in beekeeping. A deep box full of sealed honeycomb weighs about 60 pounds. A strong colony can produce up to five of those in a season, depending on local conditions. Moving and harvesting hundreds of those boxes can be back-breaking work, even with a boom on your truck. Most of us have a little brighter opinion of honey than the friend I quoted above.
Bees making extra honey are happy, happy bees.
A strong nectar flow is like a rising barometer. It picks everybody up a little. All is right with the world when the comb is filling up with honey. Honey is nectar. Bees bring home nectar that is about the consistency of water and only a little bit sweet.
