Re: 2 Out of 3 Dead Today
#1 - Completely Empty with food stores - Sounds a bit like absconding to me.
#2 - Full of dead bees and food stores - Clasic of either starvation or poison. Do an autopsy on them to figure it out. Were the bees in contact with the honey, and was the number of bees low? If it were starvation they wouldn't be in contact with the honey, if it were poison they would be in contact with honey and dead brood too.
#3 - Sounds like good strong bees.
You should button those dead hives up and keep out robbers till you can go through them good.
