in my experience, the first pullet eggs may be just slightly 'bluer' than the later ones -- possibly because the eggs increase in size as the pullet gets to maturity. It definitely has never been like the Marans type of color fading that occurs during the egg cycle, because with Cream Legbars, the color ISN'T a coating like the brown-laying breeds, but a pigment that is incorporated into the entire shell and it is blue both inside and outside unlike brown egg layers.
:O)
Rinda- I wonder if the white eggs you got have any connection to your white sports.
I don't think so... and the fading is not nearly as drastic as with my Marans, don't get me wrong. It is a much more subtle fading but I still think it's there.
