Egg color

[STFD15]

I haven't been able I find any answers to my questions anywhere, so I'm hoping someone can help me here.

I have one girl that used to lay beautiful brown eggs with darker brown speckles. For the past week or so her eggs are tan with brown speckles. What could cause this and is it something I should be concerned about? We haven't changed feed or treats or anything crazy like that.

Not all that unusual or concerning - as a bird progresses through their laying cycle the color can shift like this.
