I have 7 duck eggs in the incubator. They are on day 28. Two just pipped. One of those are propped up on a paper towel, that has gotten wet (They all have detached air cells, hence being propped up). I have already had to open a couple times to refill water since I can’t get up consistently past 70% humidity. My question is, do I open and swap the wet paper towel for a dry one or let it go?
