I only have one incubator that has all the eggs in it, the 1st batch hatch day is 3/20, batch 2 hatch day is 3/21, and 3rd batch hatch day is 3/28. I will have to stop turning batch 3 on D13 if I get an external pip from batch 1 or 2, if Iam correct
Yes, once you see an external pip you'll have to stop turning the others so you can keep the humidity at a decent spot for the hatching chicks. Once they hatch they'll move the other eggs all over the place and do plenty of their own "turning" while they're in there. Lol
