Do some of my bees have CBPV? Today I watched 5 bees at the entrance to Hive D. They were on the ground below the landing board. They weren't moving much. Two or three of them were considerably darker than I'd expect.
Could it be the weather? Perhaps these bees were just chilled. Am I a Bee Hypochondriac? Certainly I have no idea whether this hive has this disease.
