I have a Little Giant, w/fan, w/turner. The instructions didn't say anything about humidity, so I went in blind. I did not candle eggs. At day 18 I removed the eggs from the turner and placed a wet sponge under the screen. 10 of 40 hatched at 20 days, and within 12 hours they were feet up, dead. This was in October. I felt the incubator did a fine job of keeping a steady temp. I'm ready to try again. I have a guage to monitor the humidity. I intend to do a dry hatch until lockdown and add water as needed. The eggs are fresh, although a few might have gotten a bit colder than desired. The problem is, I really don't know what caused the deaths of the 10 chicks that hatched in October. Any ideas of what to do, other than monitor the humidity?
