Another question for you, this time about bearding. I know that bearding is when it is a bit too hot inside the hive so a few (or many) go outside to cool things off for a bit. Is this the only reason they do this or are there others?
Also, why would one hive have so many bearding and the one right next to it does not. Would that simply mean that hive that is bearding has more bees in it than the other? Does bearding signify anything else? Just trying to understand thier behavior as best I can!!
