How exciting for you to be starting out on this new adventure. The learning centre is a great place to start for lots of articles on keeping your chickens happy, safe and healthy. Here is the link if you have not already stopped by there ~ http://www.backyardchickens.com/atype/1/Learning_Center

Wishing you the very best of luck in the future. Be sure to ask any questions that you may have, everyone here to help and very friendly.
Enjoy BYC and all the chicken chat
