Okay, so my day 28 was 2 days ago. Only one egg (of five) had a slight crack, that I could see. Based on where the other pips are, it's possible there were other pips/cracks that I just couldn't see. 2 days later, today I have 4 pips, one of those is zipped and peeping... but still no one is officially hatched yet. One that looked like it's bill was sticking out has stopped progress and hasn't moved. Yes, I am nervous, but I haven't opened the incubator because my temp and humidity are perfect!! How long does it take to hatch out duck eggs? My chicken eggs didn't take nearly as long. However, my chicken eggs also took only 21 days to incubate. Suffice to say, ducks take longer to hatch?
