We are hatching duck eggs in a hovabator 1602 still air incubator and are on day 16 and had one explode this morning. I couldn't do anything with it since I had to go to work, so my son got the egg out and cleaned most of it up where the egg was. I need to finish cleaning the incubator up and clean the little bit of rotten egg that got on the others. The eggs were fairly dirty from the lady I got them from but I cleaned them the best I could with my finger nails before we started the incubation. Please advise what we should do......in cleaning the incubator up and how to clean the eggs up and what to use....thanks
