I have never had good luck hatching goose eggs in an incubator. I got two to hatch once out of about 10. Not sure what I did wrong. I think Porkpal is right, Let nature take it's course and they should raise you a quite a few goslings. Do you know if you have both male and female among them? The first eggs can often be laid when it's quite cold, and it might be best to just use them for cooking until the weather stays above freezing. Even though the geese ususally will cover their eggs with straw, they can chill too much. Have you ever visited the feathersite? They have lots of information about hatching all sorts of birds. Good luck and keep us posted!
