Got another question for u all, since I've been starting my chicken and duck flock I decided to purchase an incubator, I've read many books and articles on incubating eggs but still have questions. After getting my incubator to 99.5 degrees I plased 11 of my ducks eggs in it, I've put the water in the bottom for humidity, and turn them at least 4 times a day. I'm now on day 13, I've been candeling them and all but two seem to be moving inside the egg. The two eggs that do not move have a dark spot in the middle and appear to be dead. I do not want to remove them without being sure that they are dead embryos, but I don't want to leave them in with the others if they are dead, taking the chance that they effect my living baby's. Any advice
