Heidi Kooy lives in a fairly dense part of San Francisco - her row house touches her neighbors'- with just 1000 square feet of backyard, but she manages to squeeze in an organic garden, fruit trees, chickens and, most recently, a pair of goats. A San Francisco Health Department clause that allows for "two female goats for family purposes". Two years ago she bought two Nigerian dwarf goats and today, they provide anywhere from 1 to 3 quarts of milk per day for her family (drunk as raw milk and used to make cheese).
She loves her fresh goats' milk, but Kooy admits the price is steep. The goats themselves usually cost about $500-600 each. Then there are the vet bills and stud services (to keep them lactating). And then you need to milk them twice a day, every day. Besides the daily milkings, she takes them a mile away (often by car) to a nearby park to exercise.
