So the box said 6 saxony and in parenthesis beside it-2 extra. I assumed it was 2 extra saxony but there are 2 birds with distinctly different feather colors. The pic shows two of the 6 light buff saxonies and the two darker in question. Any ideas what the darker birds are

or do different saxony lines present differently?
