Today was hatch day, but I don't think there are any pipped. It's hard to tell with a broody, but I went out and listened and heard nothing

and also I have a question for you experienced hatchers. Last time I hatched eggs, they were in an incubator. And they started the hatch in the egg turner - long story- but then I took the eggs out and put them in the incubator in cartons. On day 25, only 3 had hatched out of 24. But I wanted to see if they had just not developed or what. So I opened the remaining eggs and found that there were fully developed chicks in about 8 other eggs, but of course they were all dead. I was just wondering what happened? It looked like they were in the wrong position to hatch? Is that from being in he egg turner or the egg carton or what??? Just curious.
