Found this informative article - great news to millions of caged chickens in our nation who never get any semblance of appreciation for putting breakfast on our tables. Now, though not a complete chase the birds out to play, this movement truly builds a solid beginning for more humane chicken-care for more than a few, very hard working hens among us.
Check out the chicken sites online; the 'keeping of city chickens' is a solidly growing movement across our nation. You will be amazed at the cities that are bending to the pressure from an increasing number of people who want fresh eggs to supplement their grocery store filled fridges - not to mention the learning and enjoyment garnered from chicken-keeping.
As always...Nature prevails.
