Here’s a 2 page article  from ‘The Beekeeper’s Quarterly’ a few years back I recently stumbled 
across:

As far as moving eggs, both Mark Winston and Eva Crane do write, and give sources in their 
bibliographies, that it does sometimes happen. 

 (....and of course there is a lot of discussion in the archives as to whether or not that occurs.)
