That's a very good sign when they pip! 2 of mine pipped a day early but actually hatched on hatch day.Sounds like you are doing pretty well. I have one pipped so far. I could also hear chirping. My hatch day is tomorrow. I will post some pics this weekend when I get them to the brooder.
Remember I had 1 more that I was worried about? Well, it JUST finished zipping and kicking its way out of the shell. I am beyond thrilled that they all hatched by themselves! All 4 of them look like their daddy, a splash silkie. Momma is a blue so I was expecting 50% blue and 50% splash. They are super cute but still wet so pictures will be added when I put them into the brooder.
Here is a picture of Momma and Daddy though:
