For those of you that overwinter in singles, is it too early to push them down to one story? I started last week so i could put medications on, but they're still drawing a little comb and theres about 3 lbs of bees on the front of some hives. I'm worried about them running out of room and/or swarming. Just seems a little too early. I'd like to hear from some other beekeepers in the area.
