Preheat oven to 375°F. Grease a 2 or 2 ½ quart casserole dish and set aside.
In a large saucepan, break up sausage and saute until browned and cooked through. If there is a lot of grease, drain all but a couple teaspoons. Add onion, celery and apple, a pinch of salt and pepper and ground fennel (if using). Saute, stirring occasionally, until tender.
In a separate bowl, whisk eggs, thyme, parsley, chicken broth, and ¾ teaspoon salt.
In a large bowl, combine bread cubes, sausage mixture and chicken stock mixture. Toss gently until all the bread is moistened.
Place half the stuffing in the prepared casserole dish. Top with half the figs, then repeat with remaining stuffing and figs. Place the pieces of butter all around the top, pressing some down in between the pieces of bread. Spray a piece of foil with nonstick spray and tighty cover the stuffing.
Bake, covered for 25 minutes. Remove the foil and bake for an additional 20-35 minutes. The stuffing is done when the top is golden brown and the inside has reached your desired level of doneness. This will vary based on the size of your dish and whether you want your stuffing more crisp or more moist.
