For the chicken, economical way is to use quarters, separated, about 6 to 8 cover with about 2 inches of water (any extra chicken after this, freeze and use in another recipe). Boil them up in large pot. Optional, to make a really good broth and juicy chicken, add Trinity (an onion, celery, and a carrot, all roughly chopped). Allow to cool to room temp, remove skin and bones (good dinner for your dog) and roughly chop the chicken. Stain the broth, measure out 2 cups for this recipe, put the rest in a jar and cover and place in your fridge for the next recipe.
Preheat your oven to 200 C. Add the butte to a 9x13 baking dish and put in the oven while it is heating, remove the dish when the butter is melted, see, you just saved yourself a small sauce pan to wash.
Remove dish from the oven and place the chopped chicken in the dish. In a mixing bowl, whisk together the flour, milk, salt, and baking powder, pour this over the chicken in the dish but do not stir or mix in, think of this as a chicken cobbler.
Same mixing bowl, mix together the soup and chicken broth you made, pour this over the casserole, but once again, do not stir or mix in.
Bake uncovered for 35 to 45 minutes, done will be indicated by a nicely browned top and bubbling on the edges.
Remove from oven and let rest for 5 minutes, serve, and enjoy.
