Hi and
Learning how to raise chickens is a process, and it takes a while. There are of course many different ways to go about it, so I'll tell you what I did.
This is the first thing I read about chicken keeping. Basic info but very helpful for newbies:

Next you could go one of two ways. Your first option is to purchase a book on chicken keeping. There are lots. I have the My Pet Chicken Handbook which is great. A more in depth guide and a classic is Storey's Guide to Raising Chickens by Gail Damerow. You'll learn a whole lot from it.
Your other option is to surf the web for chicken blogs. There are some absolutely wonderful blogs that have so much good (and free) information. Three I love are The Chicken Chick, Fresh Eggs Daily, and Tilly's Nest. They all have Chicken Care Guides for you to browse.
My one piece of advice is not to get overwhelmed. There is a ton of info out there, some of it repetitive, some of it contradictory. If one source tells you that sand is great as bedding and another tells you it's horrible bedding, don't panic.

Just do a bit more research if you'd like and form your own fact-based opinion. Also, books like Storey's Guide have whole chapters on more specialized chicken keeping, like raising chickens for meat and butchering. If that's not something you're thinking about, then focus on what's pertinent to you. You'll read about all sorts of illnesses and problems (eggbinding being one), but know that though you should inform yourself about these things, your own chickens are not going to get all these illnesses, or even half of them.
So search through the blogs I mentioned and buy a book or two. Take your time...there's no rush. Pretty soon you'll feel like an expert!
Also, use BYC. The Learning Center on one of the top tabs has lots of great articles for you to read at your leisure...and if you have a question, search through the forum. We're here to help
