All-we are brand new. First batch of 24 eggs and today is day 21. We have one little beak poking out, 2 eggs with small cracks. How long does it typically take for a chick to get out of the shell? The one with the beak out is still chirping, but has been working over 12 hours now and only has a small hole. Is this normal? Thank you so much for this website and for your advice!!!
