The best book on poultry keeping, in my opinion, is Harvey Ussery's "The Small Scale Poultry Flock" It does incorporate some
permaculture principles as they relate to chicken keeping, but is not a
permaculture intensive book.
There is a wealth of knowledge here on permies.com on chicken paddock rotation, building forest gardens for chooks etc.
