Re: moveing hive
A half mile is about the worst. Are there other hives still at the old location? If so the ones who don't figure it out will go there and it won't be that much of a loss. If not, they tend to go back and then circle to find the new location, however a 1/2 mile is a lot of spiral circles to get back... where 100 yards isn't so bad...
Still anything to get them to reorient will help. Branch. Knocking the hive around... etc.
