Laying lighter eggs

[girlychick]

Hello,
We have two red star hens lately the color on the egg shell is lighter. They are 16 months old. Could this have something to do with molting? Or is it something else?

during molting sometimes, they egg color will lighten. Once the molt is over and they are back in full procuction, it will get darker again.
