I set runner duck eggs for my first duck hatch. They were due to hatch on Tuesday (16th). I had 3 hatch on Monday, 3 on Tuesday, 3 on Wednesday, 1 on Thursday, and 1 is hatching now (Friday). All of the ducklings are healthy and vigorous, but after 5 days of hatching the incubator is really starting to stink from all the egg goo, etc. Do duck eggs usually straggle this much? I picked these up from a friend, who carefully collected them for 7 days and stored them in an egg turner until I picked them up, but the house wasn't air conditioned and I'm wondering if some of the eggs developed a bit before I set them all on July 19. Just curious, I had promised someone they could borrow my incubator starting today and I've had to postpone until this last little guy finishes up and dries out! And it's funny to see the size difference in ducklings from the same hatch, but 4 days apart in age.
