Reduce the heat to medium.
Add the pancetta, onion, garlic, thyme, and the remaining ½ teaspoon salt to the now-empty pot and cook until the onion just begins to soften, about 4 minutes.
Stir in the flour and cook for 1 minute.
Slowly whisk in the broth and wine.
Stir in the potatoes, mushrooms, carrots, chicken drumsticks and thighs, and the remaining ½ teaspoon of pepper and bring to a simmer.
Cover and simmer for 25 minutes.
