FOUND IT..... NOTES from OTHER SITES!! I NEVER did this though, just part of my shipped eggs links! here is the paste from the original Post!
SITES oN AIR CELL DAMAGE...
1. AIR CELL INFO for Incubation http://www.squidoo.com/mailed-shipped-fertilised-chickens-eggs-fertilized-hatching-chicken-egg A normal air cell in a freshly laid egg are dime sized up to quarter sized in a week-old or older egg, and fixed at the fat end and just looks like a line when candled.
From rough shipping it is possible to see detached, loose or rolling air sacs as seen in the picture. For those eggs, you need to change your hatch plan. They have to sit 24 hours always pointy end down, to see if the aircells will reattach, about half of them will in my experience. Either way, leave them in the egg carton for all 21 days of the hatch. Stop turning early at Day 16 not 18. It is possible to hatch chicks from eggs with detached air sacs when the cells never stabilized even after 24 hours, but were left upright for hatch. Make sure any turning is gentle, and no flatter than 45 degrees, more vertical is better! Disrupted, shattered or ruptured air sacs are seen when instead of one bubble on the side of the egg, there are more than one. Handling must be very rough in these situations and I believe can be enough to kill the embryo in the first place. These should have the same treatment as the detached air sac eggs, but don't re-candle after 24 hours, these won't reattach. Just having the air bubbles rising to the top of the eggs at the fat end while hatching the eggs vertically in trays gives any chicks that do grow chance to pip into the air cell. Likelihood of a chick hatching is lower than intact displaced air cell eggs, but worth a try if the eggs show no sign of spoilage or leaking.

Suggestions for Management of Damaged and Mal-positioned Egg Air Cells https://www.backyardchickens.com/t/501034/suggestions-for-management-of-damaged-and-mal-positioned-egg-air-cells "These eggs should then be set into the incubator in a vertical position and not turned for 36-48 hours, after that turning by tilting side to side at a 45 degree angle helps to keep the air at the top. Otherwise leave well alone and dont remove for weighing. During the second week the chorio-allantoic membrane (generously supplied with blood vessels) grows out from the chick to line the complete inner surface, including the air cell. Think of it as inflating a balloon within an already inflated balloon. The air cell is now resealed and from 15 days can be treated normally though gentle handling is needed."
