Well, the shipped eggs need to be treated differently. If you search this site there is an excellent article on that. Also, when I have incubated them my best results were when I was religious about the temps and humidity. Chickens and ducks are easy for me to incubate. Goose and turkey eggs seem to take more care. Also, do ONLY a goose hatch, when I have tried to stagger other eggs even with a hatcher it didnt turn out as well. I know there are so many variables!! What works for one might not for another. But basically just see what works for you. Experience is the best teacher.
