I have two incubators going. One in lockdown. I was turning the eggs in the other incubator when I thought I heard a peep peep. I was thinking it was just the stryo foam incubator making it as I may have rubbed it. I closed it up and heard it again. Very clearly. So I flashlighted in the window but I can't see any pips. Am I imagining it? LOL Tomorrow will be day 21.
