Preheat oven to 450 degrees. Line a pan with parchment paper.
In a medium pot, bring rice and broth to a boil. Reduce heat to low and allow to simmer, covered, for 30-40 minutes.
In a large sauté pan, combine avocado oil, mushrooms, onion, celery, carrot, thyme, sage and salt. Sauté until vegetables become soft.
Combine wild rice and vegetable mixture. Stuff ¼ of each mixture into each hen. If you have any stuffing leftover, you can place it on the pan with the hens.
In a small bowl, combine rosemary, thyme, lemon zest, salt and avocado oil.
Pat the hens dry with paper towel. Rub the herb and oil mixture over the birds.
Place the hens on the pan and tuck the wings under the birds. Roast in the oven for 30-40 minutes, until the leg meat reaches 160°F with a thermometer.
Remove the birds from the oven and allow to rest for five minutes, during which time the bird continues to cook to reach 165°F.
Serve garnished with fresh herbs and your favorite sides or on its own.
