Camping, is 56 your humidity on them duck eggs ? has any hatched yet ? I would suppound them with some hot wet paper towels, socks , whatever you use. Mist them
I had literally just plugged in the bator. I popped them in and added about a cup of steaming hot water. The window was fogged when I left. I went to lunch in town with DH. I couldn't sit with my nose pressed on the bator all day.
