Make a boxed cake as directed on the box and allow the cake to cool completely. Once the cake has cooled, cut it into small pieces and place them in a large mixing bowl. Break up the pieces by hand or with a spoon to get small crumbles.
Take the container of frosting and mix it into the crumble mixture. This takes a little elbow grease to get it all mixed in. The mixture will be similar to a dough.
Prepare a baking sheet with wax paper. Scoop out 1 tablespoon of cake mixture and roll it into a ball between your hands (this is easier if you spray your hands with non-stick spray). Place each ball on the wax paper and continue to make balls with the rest of the mixture.
Melt the candy coating in a microwave-safe bowl for 45 seconds. Stir the coating and continue to melt at 20-second intervals until fully melted. You can also use a double boiler on the stove. If you are adding yellow gel food coloring, add it now.
Using a long-handled spoon or a dipping stick, dip each ball into the candy coating and coat it completely. Tap off the excess coating and place the ball back on the wax paper. Immediately place two candy eyes, leaves for wings and a beak, and stars for feet.
Allow the chicks to set completely before enjoying (you can speed up the process in the fridge).
