Melt the yellow, orange, and red candy melts in separate microwave-safe bowls, heating in 20–30 second intervals and stirring until smooth.
Transfer each color to its own piping bag (or zip-lock bag) and snip a small tip so you can pipe thin lines and small dots without the candy running everywhere.
Arrange all the Nutter Butters on a parchment-lined baking sheet.
Pipe a small dollop of any candy melt color on the top edge of each cookie, then gently press a Nutter Butter Bite on top to form the turkey’s head. Hold it in place for a second so it sticks.
Above each head, pipe short curved lines in yellow, orange, and red to look like tail feathers. Alternate the colors and slightly overlap them for a fuller, layered look.
Using the yellow candy melts, pipe two small dots on the head and press on the candy eyes.
Add another small yellow dot just below the eyes and place an M&M or Reese’s Piece on top to make the beak.
Use the red candy melts to pipe a small teardrop shape next to the beak for the wattle.
Let all cookies sit at room temperature until the candy is fully hardened before moving or serving.
