They will all be fine. Go to work and when you come home you will hopefully have a bator full of chirping, running, sweet little fuzzies. The chicks can survive for several days without anything in the bator due to absorbing that beautiful yolk full of food. The time between pipping and zipping can be 24 hours sometimes as they take breaks. Good Luck and thanks for the pics. Keep them coming.

Agreed.
If I'm not going to be around, I usually leave the lights off so they don't get stressed.
