I set eggs in my incubator on April 13th day 21 should have been May 3rd. All the eggs were not laid at the same time I collected them over a week, then put them in the incubator. The temp was fine and the humidity was good. I tried to candle the eggs and they were all dark so figured there was something inside on May 6th I was turning them in the morning and noticed one had a hole and was starting to hatch. It took that chick 12 hours to come out of its egg and then it wanted to lay on its back (thats another post). So at the time this one was hatching 2 other eggs were making noises and them they got bumped by this chick and they stopped making noise for about 2 days. They are making noises again but there are no breaks in the shell. So I am trying to figure out why this one hatched and the others have not - they were actually collected befor this one it was one of the last ones to be collected. I am almost 2 weeks past my day 21.
