>I have a few questions, and concerns. First, will a robbing hive kill all of the bees in the hive they are attacking?
If it goes on, yes.
> They weren't very aggressive with me working on the entrance in a pair of shorts! But, my concern is for the new queen. Any chance she will still be alive?
There is the chance she is dead, but yes, there is a chance she is alive.
>Secondly, I could see the bees were coming from, and leaving in the same direction. They were not, apparently, from one of my other two hives. So, how would I go about finding the hive they are coming from?
You can beeline them, but what will you do if you find out?
> Perhaps I can retrieve the hive, if of course, it's not someone else's bees! (The nearest hives I am aware of are about two miles away in a different direction.) I'm also quite sure they will be back in the morning to try to finish the job. http://bushfarms.com/beesrobbing.htm
