My humidity has not been over 55% on lockdown. My eggs are hatching, water in tray, 3 sponges along the sides and my humidity will not go up. I had 2 eggs this morning that were shrinkwrapped. I was able to get them out and save the chicks, (I know not to open it, but could see they were in trouble). Opening the incubator did not help my humidity, but not sure what to do.
