I have an egg that has pipped but hasn't progressed since lunchtime (now going on 7-8 hours). The hole isn't any bigger than it was then. The chick is moving and chirping and trying to get out, but isn't out yet... How long do I wait before I try to help it out a little? I don't want to if I can avoid it, but I also don't want to lose the chick!!! Oh, its under a broody hen, not in a brooder....
