Why day of 16 to stop turning?
I understand the basics of the chick needing to get into hatching position, however have you noticed a big improvement with shipped eggs if you stop at day 16 vs 18?
I am assuming you Don't raise the humidity on day 16 like you do on day 18?
I've did a lot of reading on the this thread:
and sorta just picked day 16 as a safe day to stop turning. Giving the chicks more time to position. I can't honestly say if it has greatly improved my hatch rates with shipped. It's just part of my "shipped" regimen. I still get a couple malpositions even when I stop turning early. I do not raise humidity until day 18/19 depending on the size of my air cells. Shipped eggs are so unpredictable! I had received a batch of call eggs that all had detached air cells. Only 2 made to week two. But about a week before lockdown I was sure one of the eggs quit. I didn't even bother to turn it anymore and that egg actually didn't quit and hatched! But I think it doesn't hurt to stop turning them a couple days early and better to give them every little chance you can.
