To fatten all sorts of Fowl in fifteen days, whether Hens, Geese, Ducks, or others; from All-Hallows till Lent.
Take Nettle leaves and Seed, gathered and dryed in the proper Season, which beat to Powder and sift; when you would use it, make it into a Paste with Wheat-Bran or Flower, making it up with Dish-water; for want of it with warm Water; give it to your Fowl once a day, and you will see the effect.
Another way to fatten Fowl.
First put them into a Coop, and three times a day give them to eat a sort of Paste made of two parts Barley, and one of black Wheat, or Millet, ground together, the Flower sifted and the Bran taken off, of which make bits rather long then round, of a convenient size, and give them seven or eight a day, and in fifteen days or thereabouts, they will be very fat.
