We have one egg that has been rockin since yesterday and this morning (super quite in the house) I hear chirping. Go over to the bator and that same egg is still rockin and when it rocks it would chirp. I cannot see anything that would suggest any attempt at getting out of the egg. How long now??? This is one of my "F" eggs (from where I got it) and this would be day 20 for it and it's 4 other partners. Our "B" eggs are on day 19, there are 12 of them.
