It started off with growing a few tomatoes on the deck of your big city apartment. Then some people graduated to raising chickens for their eggs. Now, people are running full-fledged farms in their urban backyards. According to Time magazine those urban farmers who started off with the chickens, just couldn't get enough. Now the big thing is pygmy goats, rabbits, pigs, bees, and ducks. This latest development is being called Urban Animal Husbandry. It means breeding and raising livestock. People have been doing it for thousands of years; now, they're doing it in cities. On some of these urban farms, the animals are being raised for what they produce, like milk, eggs or manure. Others are raising livestock for meat. Novella Carpenter wrote the book on Urban Animal Husbandry called Farm City: The Education of an Urban Farmer. She says people want to be responsible meat eaters, and it's empowering to grow and butcher your own dinner. She also says that growing your own meat means you're helping the environment by cutting down on shipping costs and bypassing the factory farm system, which is a huge contributor to pollution. Most people don't take it that far though. Out of the 700 members of the Backyard Poultry Association, only five are raising their chickens for meat. Not everyone is behind backyard farming. City officials have had to start coming up with rules for farmers after neighbors complained. The biggest problem is the goats. Pygmy goats can be extremely destructive, especially if they escape and run wild around the neighborhood, eating everything in their path. They also have a particularly musky, smelly odor. The critics are also worried that allowing goats into the neighborhood will pave the way for larger animals like llamas and cows. So while city councils all over the country are trying to sort this one out, animal husbandry enthusiasts insist you have to give it a try. SO what's the best animal to start with? One expert says, ducks. They're better for your garden than chickens and their eggs have a higher concentration of vitamins and minerals.
