How is your humidity right now? Big air sac can mean shrink wrapped chick, but it doesn't necessarily mean that. If you can still see some light thru the shell where the chick is, chances are it's not quite ready yet. I can never see anything but darkness where the chick is in my eggs, and I can only see light through the chick-part of the egg until about day 19.
Did you have any temp dips or a slow temp start?
