I'm still in my first year so I can't be sure of anything, really. But one hive is much lighter on stores than my others. Most beeks down here don't leave a lot of extra honey on in the winter because the winters are generally so mild. But, with the weird cold spell we had I was concerned. Also, who knows if we'll get another before winter is done. The next true nectar flow isn't for another month or so, I think, although I do see them bringing in some pollen. The hive appears to be strong otherwise with a laying queen, plenty of workers etc. Maybe I'm worrying for nothing.
