Last week we had a warm up and so we opened up the hives for a look. This is our first winter. Two of the hives (one of which was the weakest I thought) are still alive. But our top bar hive and what I thought was our biggest strongest hive are both dead. The strong hive had almost no dead bees in it. Maybe like a hundred or so. But, outside in the snow, and under the snow were piles of bees. I have done some looking around and it sounds like this hive could have died of nosema. But, I would like some opinions on that.
It had two deeps and one medium on it. The bottom deep is totally empty. Eight frames of clean empty drawn foundation. The top deep and the medium seem nearly full of honey. My question is, can I move those two boxes of honey onto the other two hives? I expect they need to be fed something in those two. Or, will I spread some disease?
