My father in law and I are hatching some bared rock eggs for the very first time with his homemade incubator. We have used the "dry" method. We have candled the eggs twice and seen devolopment (or at least what we though was devolopment). We are at day 21. The incubator has been closed for the last two days and no turning the eggs. I have seen many times on the forum people talking about seeing the eggs rock and hearing the chicks. We have seen or heard nothing. Is this normal or a bad sign? Anything we should be doing besides waiting?
