I remember when I first started hatching eggs, I waited and stressed over them. Had bad results a few times, since then I just put em in the bator, add a little water every 2 days or so and on the 18th day take em out and put in another bator for "lockdown". I noticed some eggs will rock, some wont, some pip and you wait for what seems like an eternity, and then hatch. Some pip and zip and come right out. It is trial and error and when you find out whats best for you and your environment, you will have great luck. A lot depends on the eggs too, if they were shipped and the conditions. I keep my eggs at an optimal temp if I am going to ship till I have the order complete. I used to "help" chicks when I felt they were in need during hatching. I rarely do that anymore only because I found that the natural process of hatching is tough on the baby but something they need to do. Sometimes if they are not strong enough, or something is wrong with them, they dont need to hatch. Its a call you have to make. Good luck though, I'm sure you will have good results next time.
