Perdue
Recently hatched, antibiotic-free chicks, raised and housed on a Perdue-contracted farm in Laurel Delaware, are photographed on Thursday, Feb. 18, 2016. Perdue is in the final, decade-long push to phase out most antibiotic use. At their facility in Salisbury, Maryland, one of the nation's first and few antibiotic-free industrial scale hatcheries, Perdue cranks out a million chicks per week to be delivered to local contract farmers to raise to slaughter weight.
