I've did a lot of reading on the this thread: https://www.backyardchickens.com/t/704328/diary-notes-air-cell-detatched-shipped-eggs 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.Rubynala, 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'm a little confused by the candling pics. The one on the left is on day 6? The air cell on that egg looks huge for day 6! And can you take a pic of the air cell on the egg on the right, please? (I don't know if it's just the pic) but which end has the air cell on the egg on the right?
