Two days ago I noticed a great number of bees at the entrance of one of my
four hives. When trying to open it, practically all the bees existing
inside left the hive. The queen was gone, no honey and even no brood
remained.  My conclusion was that there had been an attack of other bees
who stole everything from my hive (actually my weakest).
I checked the other 3 and one of them was in a bad state, too. The queen
had no wings, the number of bees was much smaller than one week ago, but
there still is honey inside. What is the best thing to do now? Give up this
queen and try to merge the family with one of the remaining two?
