I have 20 eggs starting to hatch in my incubator. The first chick tried for over 24 hours to get out. It's membrane completely dried out and we ended up having to help it hatch. The second one has been trying to hatch for over 12 hours. I am afraid the humidity level is off in the incubator. I live in Nevada and we have like zero percent humidity, plus we are in a/c. What should I do, chicken experts?
