Pilgrim's Pride's home roots in the small town of Pittsburg, Texas, perhaps explain why it is the largest chicken producer in the U.S., even ahead of competitor Tyson Foods, Inc. (NYSE: TSN) in Arkansas. In 1946, Lonnie "Bo" Pilgrim dressed like a standard Pilgrim and tucked a small chicken under his arm when completing orders for customers. He gave away free chicks when he sold chicken feed as a way to expand his market for chicken feed. As of today, Pilgrim's Pride operates chicken processing plants in 13 states and Mexico and processes 44 million chickens per week, resulting in 9 billion pounds of chickens per year and over 528 million chicken eggs per year.

Pilgrim's Pride's operations are almost exclusively located in the U.S. close to its farms, and it has become the second-largest chicken supplier to Mexico as well. It does have processing plants in Mexico and Puerto Rico. Along with such huge chicken-producing numbers come a few problems, as a huge product recall in 2002 due to Lysteria contamination killed seven people and made over 40 customers sick. In 2004, more than 24,000 hens were destroyed after a strain of avian flu was found in Hopkins County, Texas.

Pilgrim's Pride is still based in the same location where it was founded over 60 years ago, but today stands as a completely vertically-integrated company: it owns every process and facility from egg to table, as it says. Wal-Mart Stores Inc. (NYSE: WMT), Publix Super Markets (OTC: PUSH) and KFC, a division of Yum! Brands (NYSE: YUM) ,can be counted as some of Pilgrim's Pride's largest customers.
