I am trying to hatch duck eggs for the first time. I don’t think there’s much of a chance of them hatching but I’m trying anyway. I have a couple that are really dirty, should I clean them before incubating or will the bloom protect the eggs from bacteria? Also I’ve seen mixed answers on the humidity level for the incubator, should I start with 35-45% humidity or should it be higher? Any other tips or advice is appreciated as well, I’m completely new to this.
