Count me in for the library bunch. I have been reading library books for the last two years, some of them checked out more than once over that period, but I have only bought one book and that is because it has the most information about the most subjects of all the books I read. I finally bought City Chicks, by Patricia Foreman, because it covers everything including diseases and how to treat them. Some of the books sounded really good when you read the review, but most of the time they didn't live up to the hype. I would rather "borrow" a book until I know for sure that it really contains the information I need. Some of the most popular poultry books were a waste for me, so I returned them mostly unread, and I wasn't out $25.
You are better off reading books to help you use the Internet effectively. There's so much you won't know enough about to even do a proper search until you read up on the subject of chicken keeping. I grew up on a farm where we kept chickens for eggs and meat, but I was totally unprepared for raising day old chicks in a cardboard "brooder" box, except for I had a library book with a brooding journal of what happens daily from brooder set-up and getting the baby chicks, that went all the way to moving the chicks to the coop and run. So many things can happen to little chicks so quickly that you might not have time to do an Internet search before something irreversible happens.
