Check the local feed supply stores. Some have quite a few varieties available, usually requiring that you purchase a minimum of 6 chicks, which is not such a bad idea as chickens are flock animals. There is a local hardware store near me where I can order any breed that the hatchery has available. The good thing is that the hatchery overnights the orders to the hardware store, so I get the chicks faster than if I were to place my own order with the hatchery.
Do you want a specific breed of chicks, or just a mixed colorful flock?
You can also go to your state's thread and ask around. A lot of folks hatch chicks to sell in the spring.
