In this book, Andy Lee demonstrates that a market gardener can raise chickens. Sadly, his chicken tractor design (Chapter 3) is both too heavy and too fragile for use in even such a mild climate as western Oregon. It is also too tall to step into, but too short to walk into. No animal pen should be so difficult to work in.A better chicken tractor design can be found in Joel Salatin's _Pastured Poultry Profits_ or by searching the Web.A better book on raising chickens is Gail Damerow's _A Guide to Raising Chickens_, which I consider the best book for a novice to chickens.
