Dress, clean, and cut up two fowls or chickens. Put in a stewpan with one-half onion, sprig of parsley, and bit of bay leaf; cover with boiling water, and cook slowly until tender. When chicken is half cooked, add one-half tablespoon salt and one-eighth teaspoon pepper. Remove chicken, strain stock, skim off fat, and then cook until reduced to four cups. Thicken stock with one-third cup flour diluted with enough cold water to pour easily. Place a small cup in centre of baking-dish, arrange around it pieces of chicken, removing some of the larger bones; pour over gravy, and cool. Cover with pie crust, in which several incisions have been made that there may be an outlet for escape of steam and gases. Wet edge of crust and put around a rim, having rim come close to edge. Bake in a moderate oven until crust is well risen and browned. Roll remnants of pastry and cut in diamond-shaped pieces, bake, and serve with pie when reheated. If puff paste is used, it is best to bake top separately.
