I call this personality type "instinctual." Their wild drives are still strong. They're very productive and hardy but not always the easiest to manage.
Your broody setup adjacent to the coop sounds perfect. I always seperate my hens and have had issues with the eggs when I haven't. First, having to constantly disturb the hen to take unwanted eggs out of her clutch. Then other hens crowding onto the nest daily and some eggs ending up pushed out...
