I recently purchased a fan forced air incubator. We set it up & ran it for 3 days to make sure that the temp. was well regulated. Since we were waiting for some eggs that we ordered to arrive, we decided to give some of our home grown eggs a try. the first three were candeled at 10 days. we didn't see anything, but we left them for 4 more days. Still nothing. we broke them open and noticed that they began to grow, but somewhere along the way they quit. I've since tried it again with 2 more eggs, and after 11 days, there seems to be nothing going on inside. does anyone have any suggestions???????
