Chicks died at hatch. Ideas?

[BYC910]

We are new to guinea hatching and we had three hatch, but they all died before they dried. Two others died after piping it appears and one died after zipping. I am not sure what is going on or what we can do to prevent this.

@dan26552 just hatched and grew some out maybe he can help.
