Lets preface this with... No, there isn't someone playing a joke on me, I watched her lay a white egg this morning. So let's not get into a spat where I'm being told a change in shell color can not happen.

One of my NHR's has started laying white eggs this week. She's been laying brown eggs since fall, though a lighter brown than the other NHR's but they were still brown. The 2 she has given me this week are the same off white my silkies lay. I was confused on Monday when I saw the first one because everyone old enough to lay in this run don't lay white, and they are BIG, double yolkers, much larger than what a silkie lays. I scratched my head and just thought it was a fluke or she got upset before she laid color over the shell, it was a fairly thin shelled egg after all.
Then this morning I hear a rukus outside and decide to check it out. There was Bertha, screaming at the top of her lungs in the nest box. Not sure what to do I just sat and waited, a few minutes later she lays another huge white egg in front of me. It's thin shelled as well and she was screaming until I managed to get her in hand and calmed down. Boy that was a chore.

Now, since I actually saw this egg come out of her....... What causes this? Is she just laying them a little early and not finishing the outer layer of shell because they are so big? Is there something wrong with her? She hasn't been laying well for a month almost, she's only a year and 3 weeks old, we haven't changed anything, no creepy crawlies, everyone has been wormed and treated for lice, no stress that I can tell.

Stumped.
 
this should not make a difference, but have you changed her diet? The reason I ask is because there is someone on here that has chickens that lay dark eggs and before he sells them certain times of the year, he changes the diet to make their eggs even darker....he wouldn't say what it was even after sevreal ppl. asked him. He said it was his secret. I did not go back on that link, he was not playing fair. We are all here to ask questions and help one another.

The two white eggs on the back row are Bertha's from this week, she normally lays one the color of the last egg to the right on the bottom row. The rest are from today and the one blue eggs to the right is usually my largest egg, XXL we call it, everything else is your normal run of the mill XL egg.
 
I have a couple of wheaten ameraucanas whose egg color has gone from a beautiful blue to almost a pale blue/white.

I think it's all a part of the laying cycle thing.
 
Would the change happen this fast? I did get a brown egg from her last week. One whole brown egg.... for the entire week.....
 
The color of the egg shell is genetically determined. The yolk color is feed dependent but I don't believe changing of a birds diet has anything to do with the egg color. I have noticed that my older (5yr old hens) lay much lighter colored brown eggs than they did a few years ago. Since the color of the egg is on the exterior of the shell, perhaps the glad that adds color to the calcium of the shell tends to 'wear out' as the bird ages. Can't find anything scientific to back that up, just a guess based on observation.
