So today is day 21. At about 2 in the morning the first chick pipped, and now six have pipped (13 hours later). However, most haven't really gotten any farther, and none have hatched yet. The biggest hole is about the size of a nickel. Is this normal? When should I start worrying?? Anyone have some anecdotes that can help me calm my worrying mind?? Anything helps, and thanks in advance!
