Summarize:

You can use geese to hatch their own eggs, but doing so can be expensive and difficult since geese do not lay while sitting on their eggs. Muscovy ducks provide the ideal conditions. Turkeys and chicken hens can work well, too. Natural incubation is believed to produce the best results overall, but if you cannot use natural incubation, artificial means will also work. Make sure that the hens you use are already broody. In other words, they need to have laid enough eggs of their own for their natural instincts to kick in and demand a period of brooding. For a Muscovy duck, place six to eight eggs underneath her. For a chicken hen, you can only fit about four to six eggs. If you do use a goose to hatch her own eggs, you can place 10 to 15 eggs under her. If using ducks or chicken hens, the eggs will be too large for the birds to turn naturally. You'll need to turn the eggs by hand on a daily basis. Wait until the bird leaves the nest to eat and drink. After 15 days, sprinkle the eggs with lukewarm water when you turn them. After the tenth day, pass the eggs under a bright light to look inside. Infertile eggs should be discarded and fertile eggs should be returned to the nest. Incubation can take 28 to 35 days, and hatching can take as long as three days. Keep the conditions of the nest clean throughout this entire period and continue turning the eggs each day during the entire process.
Use Muscovy ducks, when possible. Lay the eggs under the bird. Turn the eggs by hand. Candle the eggs. Wait until the eggs hatch.
