Preheat the oven to 375 degrees, cut away the packaging from your thawed chicken.
Using a cutting board and a chef's or boning knife, grab the chicken by the tail and begin to cut just to the right of the tail. You will be surprised by how easy this is.
Cut straight down half way through the bird they lay it breast side down and continue to cut next to the spine. If it is not cutting easily you are either too close to the spine or too far.
Once the first side is cut away stand the bird back up and begin to cut along the backbone one the other side of the tail.
Again, lay the bird breast side down and cut next to the spine.
Once the spine is separated from the bird you can lie it flat, which makes it cook more evenly. Drizzle both sides with olive oil and season with thyme, salt, and pepper.
Place the chicken in a 9x12 backing dish, skin side up and bake for 30 minutes.
While the chicken is cooking, dice your onion, celery, and carrots.
Add the rest of the seasoning, millet, melted ghee, stock and wine to the mixture.
Press the stuffing into a 12x16" pan. Remove the chicken from the oven and place it over the stuffing. (You may need to pin the wings down with toothpicks). Tent with foil and bake for 45 minutes, remove the foil and bake for another 45 minutes.
Remove from the oven and check the temperature of the chicken in the deepest part of the thigh away from the bone. It should be 165 degrees. Let the chicken rest for 10 minutes before serving.
