I'm so worried. This is my first time hatching out eggs from my Rouen pair ( or any duck eggs). Two were pipped yesterday when I left for work. They were rocking a lot at that point. By the end of the day, they had all pipped, and the pips on the first one had gotten a little bigger. I though for sure I would have a couple of them out by this morning, but none of them have made any more progress overnight. Is that normal? Were they just sleeping and resting up for a big day of busting out today? I need some reassurance!
