I am a new hatcher and my first hatch I tried waiting 5 days before turning and out of 30 shipped eggs only 5 hatched. All of the eggs from my own flock hatched. I have some in the incubator now and this time I started turning on day 1 after they rested for 24 hours. So far I have more viable eggs this time around so maybe next week ill know for sure. I just like experimenting. All of my own flock look good too.
