I am hoping somebody can help us out. My son is using an incubator to hatch a couple of duck eggs. Problem is that he isn't sure when he put them in (his first time for hatching). We think they are around 22-27 days. One of the eggs looks different when he candles it, kind of has some dark spots that he says are new. I am going to try to post some pictures, could anybody tell me if it looks like the duckling died or is it still alive and we need to wait? I'm going to try to figure out how to post a picture. Thx
