Chick-fil-A to serve antibiotic free chicken within 5 years

Chick-fil-A says it will serve only antibiotic-free chicken within five years, and it is working with suppliers to build up an adequate supply of birds. It is asking suppliers to work with USDA to ensure that antibiotics aren't administered at any point in the hatching and raising process. Tyson, Purdue and Pilgrim's Pride are among Chick-fil-A suppliers.
