These are done wtih 5 colors of royal icing in 2 different consistencies. I started with a 20 second icing (brown) in a squeeze bottle to cover the body of the turkey, then while the brown is still wet, I made dots in yellow, orange and red and used a toothpick dragged along the bottom of each color group to create a feather effect and added a small black eye with 30 second icing piped with a #2 tip. After drying for about an hour, I added the wattle, beak and legs in 30 second icing piped with a #2 tip.
While it's important to act quickly when the brown body is complete to get smooth results, all is not lost if you have to step away after you've laid down the brown icing and it's dried! You can still make a really cool turkey with raised tailfeathers by laying the same sets of yellow, orange and red dots in rows touching each other and dragging a toothpick through the center of the each set of dots, starting just above the yellow/orange transition.
