My duck eggs have been on lock down for approximately 24 hours in my home made incubator. I can now smell (from the outside) that there are 1 or 2 that are stinky. All temp. & humidity levels have maintained wonderfully throughout the entire incubation. I dare not open the lid but I have heard that the stinky/dead ones can contaminate the healthy ones or even explode. Is this true? Is it okay to leave them in there or will they contaminate the healthy ones? If I need to take them out, what do I do? I don't want to open the lid and "shrink-wrap" and kill the healthy living ones :/ ???? Help please.
