I had eggs that I just knew weren't going to hatch. There was 8 that I candled and didn't see any movement so I took them outside to gently open them to see if I could see anything. They were all fully formed, 1 looked small but it was formed, 1's beak was totally crossed way bad. Probably a good thing it didn't make it. Then the last egg I went to open really smelled so I didn't finish opening it all the way. So all were formed but just didn't pip. Probably my humidity problems.
