Perdue
Recently hatched chickens are cleaned, sorted and prepared for transport in the Perdue hatchery in Salisbury, Maryland, on Thursday, Feb. 18, 2016. Perdue is in the final, decade-long push to phase out most antibiotic use. At this facility, 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.
