Welcome to BYC! I just joined also and so far this website is great! People will answer my questions and give me advice! :cd one thing i am bad about is giving them water when they need it and keeping it fresh!! Always give them plenty of water! It id what most of their egg is made of!
The Learning center is a great place to start, then I would suggest "Raising Backyard chickens" forum - the menu included topics that should cover most of your questions.
