I have had the same thing with my 2 hives. One seems lazy other seems on a mission. One is a little hot and the other is calm. One may cost me a divorce the other she loves. The one that may cost me a divorce dive bombed my wives dog and 2 bees stung him on the same leg. I was not going to let her know what happened but the dog told her all about it when she got home. So after $40 at Walgreen's for ibuprofen and benadryl and a few other things she made me buy. I have come to the conclusion nothing is wrong with the bees it is my wife and her dog
