Deglaze the pan by stirring in the red wine, scraping all the brown bits as you go along. Stir in the chicken broth, then add the bay leaves, thyme, rosemary and sage leaves. Add the bacon and chicken back to the pot. Bring to a boil, reduce the heat to a medium, cover the pot and cook for 20 minutes.
Add the cipollini onions and the mushrooms to the pan and cook for 3 to 5 minutes until the onions start to caramelize and the mushrooms start to brown. Stir in the garlic and cook for 30 seconds until the garlic starts to get aromatic.
Season the chicken drumsticks generously with salt and pepper and add to the pot. Cook the drumsticks on both sides over medium-high heat, until they start to brown, about 3 to 5 minutes per side. The chicken doesn't have to be cooked through as we will braise it later on and will continue to cook. Remove the chicken from the pan and set aside together with the bacon.
In a large Dutch oven fry the chopped bacon until crispy. Remove the bacon from the pot but leave the fat there, if you have more than 1 or 2 tbsp of bacon fat, discard the rest.
