Managed a yard in singles this past year.  Produced more than
doubles, mostly becasue of the extra box of honey extracted rather
than left for winter.  The singles are being wintered inside.  I found that
the brood present was the SAME between the doubles and the
singles.  The differece was that the doubles had its brood between
both chambers with lots of pollen and honey available.  The singles
used most of the chamber for brood rearing, and the rest for pollen
stores.  I was very aware of colony food stores in my singles when I
pulled off my last supers,made sure to have the feed there right away.
Besides the fact that I winter my doubles outside, I feel that managing
my hives in doubles was easier and more forgiving that managing in
singles.
