This coming spring I am going to try to hatch out some Silver Sebrights. I am using a Pro Series Circulated air incubator model 4200. In the summer I tried to hatch out two eggs to see how it would go and I think that I didn't know much about really how to do it besides what the directions told me. ( Sometimes directions don't say exactly how to do something) I kept it at the constant temperature that it told me but when I was trying to put water in like it says to it split out. When I checked them to see if they were in the process of growing I got negative, maybe the rooster hadn't made the eggs fertile. If any of you have a lot of experience that you could teach to a beginner for incubating eggs with great results I would be quite happy if you shared them with me.
