Hi - We are on Day 25 here. All the chicks hatched a little late, one on day 23 and the rest on day 24. Two eggs left. Nothing from one egg, but the other is chirping when tapped, and has been chirping since yesterday. But no pip. i'm a little worried as it is so late. i'm not afraid to help a chick who has pipped, but have never intervened before a pip. So . . . advice, please. Has anyone helped a chick out who has not pipped?
