This is my first time to hatch eggs period! I have 11 quail eggs and the 1st one piped today about noon. I have had 2 more since. The last one piped just about 30 min ago and is doing the HAPPY DANCE in the incubator and I can now hear one chirping. How long do you think before they hatch? I really want to stay up and video. I am a librarian at a k-2 school and doing this for the kiddos. I promised them I would video it if possible. Just wondering if I should stay up all night!!
