white eggs from Barred Rock pullet

[ldemmert]

I have 5 9 month old Barred Rock pullets which have been laying beautiful tan eggs steadily for 3 months. Now one seems to have run out of color. The first time this happened she'd also run out of calcium (or maybe sunshine/vitamin D). The shell was very thin; that recovered, but the eggs are still a very, very light tan. The eggs are bigger the others'.
What's happening?

I've heard that the egg color gets lighter with time, and that it "resets" after a molt. She could be coming into a molt?

Interesting.

I started getting an almost white egg a few days ago. I wonder if it's from my barred rock too. No molting allowed!!

someone posted a few days ago that hatchery BR are crossed at some point with leghorns to get production birds. My BR's eggs were very light in color, nearly pink sometimes.

My Barred Rocks lay the lightest of the brown eggs we get.

Perhaps this one has a little exchequer leghorn in it's ancestry.

9 months; spring. When should I expect a molt? I suppose that could be happening. I haven't seen extra feathers, but I'll be looking now.
