Well. I have 23 chicken eggs distributed throughtout 2 incubators. Incubator 1 contains 6 very fertile chicken eggs, with 6 seb. eggs that I am positive are NOT fertile. And bator 2 contains 17 chicken eggs with 5 east indie X call duck eggs, and as far as I can tell, there are 13 out of 17 chicken eggs in there that are fertile... some I can't tell for sure yet. The duck eggs have been added recently, so I can only tell one is fertile at the moment. So I am very eggcited! Does anyone know if I should unplug the automatic turner on day 18? Thanks... it's very important that I know for sure!
