Three books I’ve read and recommend:
Storey’s Guide to Raising Chickens: Care-Feeding-Facilities, by Gail Damerow
Probably the best and most thorough resource on the subject. There’s a book on chicken health by the same author.
For the backyard chicken aficianado, Keep Chickens; Tending Small Flocks in Cities, Suburbs and Other Small Spaces by Barbara Kilarski, and Chickens in your Backyard; A Beginner’s Guide by Rick and Gail Luttman, both make for entertaining and educational reading.
