Do you know what your humidity was going into lockdown and temp? Do you have more than 2 babies in the incubator? If your incubator has a hole in the top where you can put in warm water and not splash the eggs, you can do that carefully as long as you are not around any fans or electrical components. if for any reason you THINK the humidity is too low. However, if you don't know the humidity level, too much humidity can shrink wrap them. In a styrofoam, usually enough humidity is a big problem. Do you have moisture droplets on the window? Was there a tray in it for humidity water? I try very hard to NOT open the incubator or help the babies until day 22 /23 as sometimes it takes longer if the temps have been low. And the danger of their not absorbing that life sustaining yolk is so important for their long term vitality. I'll check back later and see how this is going for you. Keep us posted. Good luck and prayers your way.
