Chickens are descendants of jungle fowl. For hundreds of years chickens lived in the wild without antibiotics. The modern chicken has been selected since the 1950s on a diet loaded with antibiotics. In the industry's drive to produce chicken at a lower cost, antibiotics in the feed have become a critical tool in breeding lower cost chickens. The net result of 60 years of antibiotic-based selection is a chicken with a severly compromised immune system which could never survive in a barnyard without antibiotics. At Pollo Rosso, we never feed, or administer in any form, antibiotics to our chickens. We needed to find a breed of chickens which had never been selected on antibiotics. Again, we went back to our chicken roots.
