I would do some research and decide what you are looking for. Another thing to look at is what your area will allow - roosters/no roosters, number of hens, etc. You should also just start looking through this great site and asking questions. There are so many people on here that have great information, ideas and encouraging words.
If there is a local feed supply store or TSC near you, they probably have baby chicks soon or maybe already. Some might have sexed chicks and some might have straight run (mixed male/female).
