I had one this most recent hatch that made it to lockdown. I set it aircell up from day 1, which i think was the wrong thing to do. It was terribly malpositioned. I assisted 100% even made an internal pip for it. The yolk was fully absorbed when it did eventually come out. It died in the incubator within a few hours.
The only thing i can suggest is for the first 18 days incubate as normal and hope it pips directly to the shell. I've had lots do that and hatch perfectly fine on their own, though not with the air cell in the wrong place.
Hopefully yours turns out better than mine did.
