I have a reasonably strong hive that always has a lot of bees hanging around the entrance. Mostly they are upside down close to the base board and just sitting there, not fanning but kind of vibrating, and moving their front legs.
I observe this behaviour when it a cool day and at night. So I am not sure if they are bearding. A lot more when it is hot, which is understandable.
The bees in the hive next door don't do it.
I'm just curious as to what this behaviour might mean? Or if its just normal bearding?
