Your thread had me wondering if Project Gutenberg had any books on poultry, so a quick search found "THE DOLLAR HEN" BY MILO M. HASTINGS, 1911. Here's the ebook : http://www.gutenberg.org/files/13254/13254-h/13254-h.htm
And here's "Feeding Poultry: The Classic Guide to Poultry Nutrition for Chickens, Turkeys, Ducks, Geese, Gamebirds, and Pigeons [Paperback]
Gustave F. Heuser". Clunky to navigate, but you can preview it: http://chla.library.cornell.edu/cgi/t/text/text-idx?c=chla;idno=2756741
