How can an exact pedigree be recorded here.

According to the current state of discussion, one would build a database with comparative material ( tempera / glair ) from Middle Ages Manuscripts and with known origin. The samples from the VMS would then be compared directly with this database ( ovalbumin / protein ). So a complete pedigree is not necessary. Of course, this is all associated with the problems described by Bernd and Michelle.
In addition, one could take over today still regionally existing, old chicken races into the database (e.g. Leghorn or Italian). The today standardized turbo chicken can be safely left out.
It should also be noted that tempera / glair was usually mixed on site. So, it was not (possibly) bought from far away, like other colors.
