Out with the animal cruelty. In with … mushrooms? These farmers are leaving factory farming behind

Lim was born in rural Cambodia, where his parents tended rice fields with water buffalos, raised a smattering of chickens and grew vegetables around their home. That lifestyle shaped his love of farming, but was a far cry from what he found himself doing as an adult, raising 540,000 chickens a year in North Carolina for Pilgrim's Pride, one of the largest meat producers in the US that supplies chicken to Walmart, Costco and KFC.
