Brownish Eggs going white?!

[ilovemybabies2]

Odd..... I have NO white egg layers. I have Golden, I have BSL, RIR, and BR, and BO. There was one chicken (not sure who, not a GSL), who would lay an almost white soft shelled, then it went hard the next day and normal in color.
Today, we found 2 nearly white eggs, one side of the egg is soft shelled? The other side is hard shelled. The other egg looks odd on one side. Is my chicken sick? Why is it turning almost all white? My chickens all seem healthy. The coop gets cleaned weekly. We wash the poop off our yard, they free range. They are feed normal pellets, oyster shells, egg shells, etc... They always forage, they act completely healthy. However today I will pay even closer attention.....
Have you had issues with this? What do you think this is about?

Here is the Poultry Site's article on thin shelled eggs http://www.thepoultrysite.com/publi...ndbook/16/thinshelled-eggs-and-shellless-eggs Nice article on causes of brown eggs shells turning white http://edis.ifas.ufl.edu/vm047 It sounds like it is only one hen, not multiple ones doing it at this point? ... so would would hope it is a problem particular to her, shell gland problem, some sort of stress / illness, seem to be the common ones.

Thank you for the article. It's been one hen, but today there were two that were pigmented. So now it's two hens. I just went out there, they are healthy and doing good, but something is just not right. We fee them lots of grapes, is that a problem?
