Eggs changing color?

We have 2 RSL and 2 BO hens - all layers of brown eggs. When the BO pullets first started laying, their eggs were lighter in color, almost a pinkinsh color. They still are slightly different than the standard brown eggs laid by our RSL.
But the for the past 3 days, one of our BO pullets has been laying eggs that are very, very light in color - almost white. They never used to be that light-colored.
What could account for this? (Today's light-colored egg is a little pointy, too, it seems!)

I'm sure what causes it, but we have the same thing happen here. The girls eggs start out a nice shade of brown and as they reach the end of a laying cycle, they get lighter in color.
As it's been going on for almost two years now, I don't worry about it.

Over time, as they approach the molt, the eggs become lighter in color. After a break from laying, they'll darken up again, most likely.

This egg is from one of my 8-month old pullets. Can she be ready to molt already?
