I am getting the impression that many people use two brood/food chambers for the winter. That is what I did last winter and all was well. I attended a "wintering" seminar with an instructor in September and he contended that reducing the bees to one box is the only way to go. So I did. Thought I would try it out and see how it fared compared to last year. We live in fairly mild climate (usually), although it is rather cold this year so far. I think that it is OK to check for food stores with the bees by opening up the colony on a day that is feeling warmer outside here (or to just lift the back I suppose). Being a second season beekeeper I am always looking for and listening to advice. What I was wondering is, that if people I am reading posts from are finding their bees in the top box already (I get the impression that they only recently have been hunkered down for winter), what about all the stores in the bottom box. Surely the bees could not have eaten up all their food in the lower chamber so soon. I understand the bees won't go down to get food. Is that true, or will they go down to the bottom chamber once they have gone up to the top. I am really quite confused about this 2 chamber system and how it works. Great day. Cindi
