Hello all. I had 12 eggs, great incubator with fan & turner. I have read everything I could find before attempting this. Temps were at 98.5 -99.5 for 18 days. Humidity at 40-45 whole time. Candling looked great. Day 18 moved 10 good eggs to lock down in separate incubator that was run at 99 degrees for a week prior. All water areas full & 3 wet sponges added only brought humidity up to 60. Day 22 first external pip & zipping started an hour later. 24 hours later, chicky died. Dry membrane- paper white. Next chick had started a zip & 6 hours later, I assisted. Only surviving chick! Autopsies showed all dry and white dried out membranes!!! No shrink wrapping. Very late deaths. We're devastated. How can I keep this from happening again? I have more eggs to go to lockdown on April 6!!!! I need help!!! Also lone survivor is sticky & wont fluff out. She's cheeping & stumbling around. I don't want to chill her, but dont want bacteria either! She's our miracle chick. What should I do? We are so worried!
