I have about ten hives here at home that range from small-weak to three fairly strong. I moved one of my stronger hives (a split I did this spring) a couple of days ago to a new location here on my farm. It had been in a pen of super tall weeds and is now out in the open. It has a deep and a medium chocked full of bees and quite crowded, as well as lots of stores. All was well until late afternoon and there were tons of bees in the air and they were super revved up. They seemed to be circling in the air and coming out of the front of the hive. It sort of looked like they were attempting to swarm. I suited up and pulled a couple of frames and bees were just head down eating from the cells. I have seen no queen cells and have eggs and larvae. I assumed robbing with all the activity, but observed no fighting, carrying off of bees etc. The only thing I saw was unusual head down eating on the frames. Then I did the unthinkable, I lifted up the hive to peer underneath the screened bottom and dumped the medium upside down on the ground. Needless to say we went to defcon 1 at that point, the dogs, horse, anything that moved here was getting stung. After a sequestration in the house, I went out before dark and there is still a quite strong "revved up" agitation coming from the hive. I find it weird that the weaker hives around here aren't getting robbed when this one is? It seems that they would be quite able to defend themselves. I am not feeding it and have an entrance reducer on it. What the heck is going on?
