Okay, so I'm hatching chicken eggs. It's already day 21, and I have not seen any signs or pipping, or heard any peeping coming from my eggs. They are fertile, and I candled them on day 18 to make sure they grew properly, and are alive-- wich they are. I REALLY need help and advice, because I do not want to kill my chicks ): I think that they have moved because when I came back from school, the eggs were in different spots. I am using a mini chick-bator from stomberg's chicks &' gamebird's website, which is:

I only have two eggs left because one was infertile. This is my second time incubating chicks, but the other time, all of them died ): and I really need help.

Thank You .
