No. Laying a light or white, or just wrong colored egg for a dark egg layer is an indication of some other issue -
I just had the same problem myself today, an almost chalky light egg in my Marans pen, with dark scratches on it...so I have to refer to my own research on the matter and here it is:
All I could find specific to egg color changing that dramatically is Nicarbazin fed to brown-egg layers turns their eggshells white within 48 hours, although this is completely reversible when the product is withdrawnfrom the feed. Even low levels of nicarbazin can cause some loss in shell color, mottling of egg yolks and a decline in hatchability.
I just added goat feed to my pet yard, the only difference in the yard, so I'll see if it has that, otherwise, my girl has just run out of paint for now - they are moulting after all!
I hope you find an answer!
