I know not to open the incubator during lockdown,I have hatched alot of babies, so I have experience. For some reason this hatch, I had 10 eggs all but one was shrink wrapped, never once opened the incubator during lock down. Temp and humidity was correct. Any ideas what could cause this? I am using janoel 12 if that helps, I also have the incubator in my bedroom, so there was no chance of it being open, and no drafts.
