You can keep them warm in an oven at low heat under tin foil if cooking a whole batch at once. I used two chickenthighs per person and cut the meat from the bone into strips
I have a halogenoven so no need for the big oven just for a few potatoes. Add stock as per your families taste, and I popped in carrots, peppers, butternut squash ( all taken from the freezer) and some diced potato, cooked for twenty minutes until all the veg was soft, poured it into a oven proof tray and topped with a sheet of pastry
