I will stand corrected but I have been told that SHB's like higher humidity, so whether the trees etc are restricting wind/air flow.
To shift hives, the rule from Sawdustmaster I think, move them 3ft or 3 miles seems to work, it may take multiple shifts but does seem to work well.
Concur OB, tis my experience in what works. Tho' I have read countless times in the past weeks of difference;"shake 'em out, and they'll walk in" and "throw down twigs and brush and they will reorientate"... all within metres of the original hive position.
Mind you I have also read much of "waaah waah, my bees are gone!!" and "this nuc was strong, that nuc was weak, now that nuc is strong and the other nuc is riddled with beetle".... beats me why some some choose to put the willow to tneir pwn back.
Well not really beats me, an explanation is found in trying to run 4+ colonies in an urban backyard and no option for a remote location shift nor time spent daily moving a colony - the kids swings being in the way.
