I saw signs of activity around all the hives except Persephone and Bubblegum. I even knocked them about a bit (a couple of swift kicks actually), but not a single bee poked her head out, so they look like deadouts.
Persephone is no great loss, especially since her queen was slated to get whacked in the spring anyway. Bubblegum, though -- that one breaks my heart. I really expected her to make it since she was one of the strongest colonies all last year. It just goes to show that you never can tell with bees.
