"Mad City Chickens"  The first of four films in the Michael Fields Agricultural Institute 2012 Summer Film Festival.  "Mad City chickens" is a  sometimes serious, sometimes whimsical look at the people who keep urban chickens in their backyards.  From experts and authors to a rescued landfill chicken or an inexperienced family that take the poultry plunge--it's a humorous and heartfelt trip through the world of backyard chickendom.
