What I also like about the Kinoshita et al. study is that the chicken breeds studied included more than just Japanese breeds. The ancestor "Red Junglefowl" and types such as Fayoumi, Leghorn and Bantam that resemble ancient breeds were also studied (see page 3, Table 1). It would have been nice if the places of origin of the chickens had been described in more detail (some are identifiable by name, e.g. Polish Bantam). I admit that my focus here is on the European region.
In Europe today, there are more than 180 different chicken breeds, although breeding on a large scale began only at the end of the 19th century. As described, there was already breeding in the late Middle Ages.
Samples from manuscripts to be compared should therefore already show a certain diversity. In the best case, the samples can also be taken from colors in which glair was mixed with the color pigments. So it does not necessarily have to be a "clear color", i.e. without pigments ( as in the VMS on You are not allowed to view links. Register or Login to view. ). Unmixed, "pure" glair is of course best for samples, but at least with the mineral color pigments, processing should also be possible.
Here is an example of a ( possible ) chicken breed from a medieval manuscript. The Red Junglefowl or similar is not white.

The use of egg white as a binder for paints was already documented in the High Middle Ages. From the time around 1100 the tract "De Clarea" has survived (Burgerbibliothek Bern, You are not allowed to view links.

Here is a Latin / German translation of the text:
