You're off to a good start -- learning about chickens BEFORE you actually have them. And, joining this wonderful community of generous and experienced folks will certainly give you a leg up (a drumstick?? sorry, I like bad jokes) when you are ready to add those birds.
Welcome to BYC; let us know when you get your chickens, please!
Good for you on doing the homework first! I second @SilverBirds suggestion to check out the Learning Center. And you should always feel free to ask questions, everyone was new at some point.
