>Has anyone split a yard in half, taken one half of the hives for rides
(commensurate with the length of travel involved in migratory trips) and
returned the hives to the same yard and then compared the two halves in
respect to all the problems our beehives have been undergoing?

Dr Zach Huang did a couple of years ago.  Don't have at the tip of my
fingers, but results as I recall did not indicate major stress.  I can't
find at his website, so may not have been published.
