Heat the butter and oil in a large Dutch oven over medium-high heat. Once the butter has melted, add the carrot, celery, onion, garlic and bay leaf. Sprinkle with salt and pepper. Cook until the vegetables begin to soften, 5 to 8 minutes. Push the vegetables to the outer edges of the pot making a "hot spot" for the ground chicken. Add a drizzle of oil to the center of the pan and then the ground chicken. Sprinkle with salt, pepper and the poultry seasoning. Cook until the chicken is brown, 7 to 10 minutes. Sprinkle in the flour and cook for 2 minutes. Add the heavy cream and chicken stock. Cook over medium heat, stirring, until the sauce begins to thicken. Season with salt and pepper and add the parsley, rosemary and sage. Stir and set aside.
To cook the puff pastry, butter and flour the lid of the Dutch oven (you want to use the underbelly of the lid). Whisk the egg and water together and brush the puff pastry pieces. Lay on the underbelly of the Dutch oven and place in the oven. Bake until the pastry has risen and is golden brown, 10 to 12 minutes.
To assemble, ladle the chicken pot pie filling into a bowl and place the a puff pastry piece on top. Serve and enjoy!
