Here is a link to my favorite condensed article that tells you
Everything I Wish I Had Known Before My First Chick. It is very helpful. You have some very good advice above. It is NOT cheep (er, cheap). But you will know where your eggs came from, and how the birds were treated.
In North Carolina, you should have a nice wide variety of chicken breeds that would thrive. There are some members in rather extreme climates (Arizona, Maine, Alaska) who have to think carefully about breeds that will do well.
Do over-build. Do be careful about predator protection. You will want your coop and run to be easy for you to access to clean. Check out the
Learning Center for more info, and LOTS of coop designs. Browse the
Forums to see what folks are discussing or to post questions in places where they are most likely to be answered quickly. And you might like to connect with other BYC members in your area, using the Where Am I/Where Are You forum, to look for your
state thread.
You are starting out right by doing some research first. Good for you guys. Best wishes with your chicken project! They are fun birds, and a good way for families to learn together.
