I've read where it takes 6 to 12 hours and sometimes longer for a chick to totally hatch, this one started about 5 to 6 hrs ago, can see is beak in the little whole about the size of a half a dime. You can see his little beak opening and closing but he/she is not even peeping, making any noise, are they usually so quite when they are trying to break through? At what point do I need to worry? I've read you should not help, is there a point I may need to interviene? Pipping is toward the small end of the egg, not at it but nearer to it, is where they usually start coming through? How will I know if it's distressed?
