I only ended up with two eggs being viable. The one ended up with an external pip on day 18 and never developed any further. The humidity being up and down must have caused it. I don't even know how it pipped as I checked it in the shell and it's beak was not near the pip hole. It was formed but still full of blood veins and egg sac that was over it in the shell. The other egg is in the beginning stages but will probably not make it either since my humidity in this cheap incubator is off so much no matter how hard I try. I am still leaving it though just to see. In the past I have gotten two ducklings that were able to hatch in it. I hope yours are still doing well.I checked my one and it is still going strong. This is day 14 for it. I added the others later so I won't check them until this weekend. There's a good chance none will even be fertile but I was trying for it not to be a loner if it makes it. Good luck with yours.
