Jackie,

I have pondered these questions for many years.  The truth is, no research exists on the topic.  Everything is speculative at this point.  That being said, common sense must prevail.  Animals should be fed what they are designed to eat.

The origin of chickens is the jungle.  Grain seeds, grass, insects, berries, and other forraging type foods are the chicken's native diet.  The closer you can get to this, presumably the healthier the bird will be for you to eat.  That is why free range is so important.  Allowing the bird to hunt and gather its food makes better sense than feeding 100% vegetarian diet of corn and soy. 

Have a great day!
