We have had a succesful couple of years raising layers and turkeys in our backyard and are now getting 20 cornishX on August 25. I plan on raising them in a tractor on grass, but am wondering if and when they will be interested in food other than grains? I have access to lots of bread and veggie and meat scraps from a restaurant, and would like to save a couple bucks by supplementing their feed with scrap. Will this affect their growth rate negatively? I plan to process them @ 10 weeks. Thanks for your ideas.
