SAN FRANCISCO - NOVEMBER 16: Heidi Kooy holds one of her chickens as she walks through her yard which she calls the 'Itty Bitty Farm in the City' November 16, 2009 in San Francisco, California. Heidi Kooy is one of many Americans that have started to raise chickens in their urban yards to try and save money on food costs during the economic downturn and to find a safer alternative to factory farmed food. Chickens provide eggs and natural fertilizer for gardens while eating the bugs that could harm the crops. (Photo by Justin Sullivan/Getty Images)
