I agree a white egg ,dual purpose breed should have a place.It would be a great project for a group of breeders to work on (White Hollands). The Barred Hollands are still around.You can also make use of California Grays and California Whites. White Hollands did exist and may or maynot still be a few.Lamonas were a well made breed that may or may not be around (another good project).Sandhill has a White Dorking strain that produces both Rose and Single Combs.If White Leghorn or California Whites were mixed in once with White Dorking,then 4 toes,yellow legs would segregate back out and allow the yellow skin,4 toes,white eggs,single combs,red lobes,etc.We still have the original combinations and information on how Lamonas,White Hollands,Barred Hollands,and California Grays were made. It only takes,time,work and effort,to re-establish or re-make these.Some originals could turn up,with some serious searching. A very worthwhile effort,but more of an undertaking for a group than an individual.
