Good Morning! My class and I are in need of help - about 2.5weeks ago we ordered duck eggs from an out of state Hatchery. At this point our eggs should be about 16days in, but 3 or 4 of our eggs appear to be further along than the 16 days when candling. Here are a few candling pics of where the air cell appears to be showing closer to the 25 day mark, please let us know your thoughts????
