Hi, This is the first time I've tried hatching chicks. There are 18 eggs in the incubator. Today is the 21st day. This morning, I heard chirping in several eggs. One of them poked a little hole at about 8 this morning. The crake is very close to the small end of the egg. The membrane is broken. So I guess she can breath. However, it is 4:00pm now. The size of the crack on the shell is still the same. And I have not seen the egg moved at all this afternoon. I am not sure if she is resting or... well, about to die. Is there anything I should do?
