My Cornish X peeps will be shipped on 9/14. I've been shopping around for organic feed and found soy-free organic feed with 19% protein which they claim is their broiler feed. Many posts I've seen recommend 20-22% protein. I plan on keeping mine in a chicken tractor for the last four weeks. From what I am seeing here, I should expect my birds to grow slower. I don't think it's easy going organic, for example the feed costs $26+ for a 50 lb. bag vs $14.95 for regular feed and in my case, I would have to drive almost 2 hours and buy all the feed I think I'll need at once. Yet if we are raising our own birds because we want safe, clean food, why would we feed corn and soy that has been genetically altered or that has been sprayed with chemicals? On the other hand, if I could boost the % of protein to between 20-22% somehow, I would feel much better about going organic if I could come close to matching the growth rate of those who do not and feed soy. Is there any way to suppliment the feeding program to get the amount of protein I am looking for and still stay soy free and organic?
