I have friends who raise a few chickens in the suburbs. A hundred years ago, people also raised chickens to get fresh eggs and meat. Here are some excerpts from the March, 1919 issue of Ladies Home Journal:
Did You Ever Think of A Meat Garden?
Why not raise meat in the garden as well as vegetables?
There is no reason why chickens cannot be kept successfully in a town or village lot, provided they are kept in the sanitary condition that is just as essential to the health of the fowls as to the health of the community. Many a family could keep a few chickens, not to make a fortune on selling eggs, but to raise this quick meat for table use or to supply the table with eggs.
The objects attained in keeping chickens for the use of the home table are fourfold: Fresh eggs daily for the children year round; increasing the food supply; raising meat in a short time for the table; saving money on the meat bill.
