We have 2 bators, and today was lockdown for 3 duck eggs so we put them in a bator that even without water has a very high humidity level(I think there is water in the styrofoam that may be doing it, can't think of anything else since we washed it when we got it)...Even without any visible water the humidity is 80-85%, temp is perfect, is that too high during the lockdown period?...The humidity was kept perfect during incubation...Thanx in advance!!!!!!!!!!!!!!...
