Color change in eggs

[Little Miss Chick]

I have noticed in the last couple of weeks that some of my eggs are changing from a light/med brown to a much lighter color. Why is this happening? I don't know which hen is laying the lighter eggs.

How old are your hens? Sometimes the eggs get lighter because they are getting close to a molt and sometimes it's just a glitch in the paint booth.
