I have a Little Giant Still Air Incubator and there are eleven silkies eggs inside it right now. Because of the cheaper incubator the temperature and the humidity will not stay constant. I finally thought I got the temperature constant yesterday, but then it dropped over night. How will this impact my eggs and their hatching rate? Will any hatch? Any tips help. I just want at least two to hatch and that would be a victory for my first incubation.
