Although, I have one that is day 17. I have been watching my chicken eggs today and I see that a few of them are doing the rocking thing. Shaking even. One of those being the day 17 egg. Does that mean that egg will hatch early? I was told not to raise the humidity etc until late tonight because of the day 17 egg. Any other advice, or does everyone agree with the advice I got. I'm anxious to raise the humidity, put my eggs in a carton and get started with this. I am a pretty patient person so watching and waiting for hours(after the first pip) will be nothing to me. I will let nature take it's course....but of course I will be bursting inside(already am)
