Changing feeds, how long to see a difference?

[columbiacritter]

We are changing from a pelleted, but quality food, to an organic whole grain feed. How long would you think it would take to see a change in the chickens or their eggs?

These hens also free range everyday on a lovely grass and clover field.

You may never see a difference if the old feed was otherwise nutritionally complete, especially seeing as how you're free-ranging them as well.

But you might. In my experience it takes about two to four weeks if there is going to be any noticeable difference.
