Prepare Bird's Nest Rolo Pretzels according to directions listed. In a small mixing bowl, using a fork, combine powdered sugar, butter and milk. Stir until well blended and smooth. Tint mixture with yellow and red food coloring to make an orange color (you will need more yellow than red) and stir until well blended. Scoop mixture into a small ziploc bag, and using scissors, snip a tiny tip off the end. Pipe beaks onto blue Sixlets.
In a small microwave safe bowl, microwave chocolate chips on 50% in 30 second intervals, stirring after each interval until melted and smooth. Paint eyes onto Sixlets using the tip of a wooden toothpick. Store Baby Birds Nest Pretzels in a single layer in an airtight container.
