They seem to take forever to hatch. This is the hardest part when we have to sit on our hands and just wait it out. Mine got over 48 hours, I had already put the air hole in the shell after it was longer than 24 hours with the internal pip. That is when I saw the labored breathing of the little ducky and decided to peel him out. It was one sticky chick with no blood vessels or egg still on its outside, just full of goo. I washed him gently off to get all of the sticky goo off of it, put it in the brooder and now it is a very large half Muscovy half Mallard/Rouen beautiful duck that is just a little over 2 months old. I was a nervous wreck hatching it out but so glad that I did.
