Preheat oven to 225°F. Place parchment paper on a baking sheet and spray with non-stick cooking spray.
Using a mixer with a whisk attachment, beat the egg whites on medium speed until they become foamy.
Add cream of tartar and continue beating.
Add sugar one tablespoon at a time while beating.
Increase the speed to medium-high and beat until stiff peaks form.
At this point, you have two options. 1) Add a few drops of food coloring and beat it into the meringue to make only one color of chicks, or 2) Divide the meringue to make different colors. Divide into thirds if you want three different colored chicks, or divide in half for two colors.
Add a few drops of food coloring, then beat until the color is evenly distributed throughout the first bowl of meringue.
Place the colored meringue mixture into a piping bag with a large round tip, and pipe onto parchment paper to make a chicken shape about 2 inches tall.
First, squeeze the piping bag to form a large base chick. Pull up on the bag slightly to set the base to the height you want. Stop pressing when the base is large enough, but do not pull the piping tip away from the base. Start squeezing again, gently, while raising the tip upwards to form the head. Remember, if you want a broader base, don't pull the tip up; keep it low in the meringue until the desired size is reached. To make a thinner, smaller head, squeeze with a light touch and pull the tip upwards.
If you have to start over, scrape up the meringue and return it to the mixer bowl, beating it again until stiff.
Repeat by coloring another bowl of meringue and making chicks in that color. Continue repeating until all chicks are made.
Bake the chicks for about 1 hour. Do not let the tops brown, or the chicks will lose their color.
Turn off the oven and cool the chicks until they harden. This can take a few hours.
When cool, make the eyes for each chick. Melt chocolate chips on high in the microwave for 30 seconds. Stir. Heat again for 30 seconds, if needed. Put the chocolate in a piping bag fitted with a small round tip, then pipe two dots for eyes.
Make the beaks for each chick by melting the white chocolate chips in the microwave using the same procedure you used for the chocolate chips. When melted, add orange food coloring and mix well. Place in a piping bag with a small round tip. Start a little below the center of the eyes and make a dot, then pull down to make a beak.
Using the orange chocolate, pipe feet onto parchment paper. Make 3 joined toes (as shown in the photo under the "Making Chick Feet" heading. Anything similar to the ones shown in the picture will work. Make them about 1/2 inch long. Chill them in the refrigerator for 5 to 10 minutes and then insert them under the front of the chicks in the frosting.
Assembly: Use a cupcake with a mound of frosting. Roll the frosting in the toasted coconut. Then, set the meringue chick into the frosting to attach it. If it isn't secure, add a little frosting or melted chocolate to the bottom of it to help it stay in place. Insert the feet under the front of the chick.
