Re: First deadout of the winter
In the final stages before death, the bees can be so traumatised there can be little clumps in different places. I won't say anything about mites since we don't talk about that.
Something different, why breed for winter flying? The only reason I could think of is so they get out and poop outside the hive. But winter flying can also be a hazardous activity, in my mind you'd be better just to see who comes through with the least nosema, for whatever reasons, and proceed on that basis. There are a number of factors that can cause one hive to fly on a cold day and another not, other than breed.
