As much as I love books, I read constantly, I would not bother to buy any chicken books.
Well, I own two... Ussery and Damerow both good reads but do contain some 'not so great' and/or outdated info. I have not cracked them but a few times since the initial reading.
Try your library, we have state wide borrowing here and can get about any title.
Better to read a borrowed copy before buying, IMO.
I read a couple dozen and very few were worth reading, let alone owning.
This website has given me more information than any book.
I read a lot of the threads and learn a lot.
This^^^ but bring your grains of salt.
I learned more here too, by readingreadingreading for hoursandhoursandhours.
I took notes and saved links in a word doc(you can search it) and a spreadsheet with headers like coops, roosts, nests, dosages, predators, etcetcetc.
But I am old school, laptop with 'real' programs installed for these tasks.
