I need some advice. We are located in Southern Colorado at approx 6,615ft. I currently have a hatch going that isn't terribly successful. I'm using a styrofoam incubator from Farm Innovators. I've had a terrible time keeping my humidity up both during incubation and now during lockdown. We had 12 live chicks at lockdown and only 4 have hatched, today is day 21. I see no more pips or movement in the 8 remaining eggs. So, once my last little dries out a bit more, am I safe to slowly open the lid to candle the remaining eggs for viability? Thank you in advance for the help!
