Thanks to your informative posts we just had a our first hatch of coturnix! Problem is we only had 7 out of ~40 eggs hatch. I am sure this is due to my 2-year old learning to open doors and leaving the incubator lid open overnight. then we had a power outage the next day for 4 hours. so these chicks came on day 20 after the above malfunctions. its now day 22, when should we call it quits on the other eggs? thanks.
