Yes, they can still hatch, though the odds are a bit more against them. I find with shipped eggs that often embryos quit around day 7. I will see 80% of them developing and get all excited just to find out that some died on day 7. I'm not sure what cause it, but I know it only happens to shipped eggs and it happens to other people as well, so I'm not comletely crazy. Like kizanne said, the rule of thumb is to expect 50% to hatch from shipped eggs (depending on the situation). I have seen 1 or 2 people get 100% hatch rates from shipped eggs so it's posible, just not very likely.
There is a difference between problems, you can have dislocated air cells in which the air cell was knock out of place so it moves as you turn the egg and then you can have ruptured air cells where the membrane has been broken, you would see multiple bubbles and the air cell would move all the way to the pointy end if turned that way. Dislocated air sacs will sometimes relocate after letting them sit 24 hours, even if they don't relocate then, they will sometimes relocate during the incubation process. The odds are a bit more against them, but they can most definately hatch. Ruptured air sacs almost never hatch. It is posible if the embryo makes it where it's membrane takes the place of the broken membrane, but embryos in that situation almost never make it that far, and usually don't even develop. Eggs with either of these porblems should be treated a little differently when turning. Place eggs with ruptured air sacs in egg cartons large end up, and don't turn! If it has any chance, then don't turn it. For dislocated eggs, turn them, but no more than 45 degrees in order to keep the air sac in a fairly relative position. Hope this helps.
See if I can do a staggered hatch, setting on Dec 11th to join the New Years Hatchalong.
