She needs her ink replaced! She is runnin' out of color! :)
Some birds lay odd colors. I had a older Buff Orpington that would lay almost a brownish white egg every once and a while. They she would lay a brown egg. I think it has to do with there egg cycles or something along those lines.

I have had EE's in the past that have layed a light pinkish egg. Some of my EE's layed green and blue as well. It just depends on the specific bird I believe.
