One of my 4 hives is always in a state of bearding. Flow or no flow, dry or humid, rain or shine they are piled 2 and 3 deep on the front of one of the lower deeps. None of the other hives will beard at all. I've been a beekeeper for five years and this one really puzzles me. I did shake a laying worker hive in front of all of my hives, but I think most of the bees when in the one that beards all of the time. The hive is really doing well other than girls on their "front porch" hanging around. Any thoughts?
