I don't have a hygrometer (or whatever to measure humidity) but, my sponges were dry when we woke up and I have had 2 hatch. I have a 3rd egg that pipped early yesterday. He is still moving inside the egg, but I think the shell may be too hard. I soaked the sponges and even sprayed warm water lightly on the egg. How long do I wait before I give it a hand? I don't want him to die in there. Oh, there is a whole where he can breathe, he made that yesterday. I know it can take awhile from first pip but with the sponges being dry and the shell seems dry, can it be too dry for them to break out? I don't have a lid so I'm not opening and closing the bator it's homemade. I just hope this little guy/girl makes it out.
