Okay take a deep breath and hold it then let it out slowly
.
What we need to know is the chick breathing normally?
You have removed enough of the shell it should be able to move slightly, is it?
Also, if the chick is making swallowing motions DO NOT do anything further until it stops. This is a sign it is absorbing the yolk.
from the picture, you are now in a full assist mode as there is no leverage for the chick to push its beak against to move and rotate. the act of chipping away at the shell as they move loosens them and allows them to move around so they can push out.
At this point, with that amount of shell removed the chick is wrapped or stuck.
In the space above the head, carefully chip away at the shell and using a small kids paint brush and liquid crisco paint the membrane looking for veins, if no veins, using the paint brush tease away the membrane from the chick. continue doing so until the chick moves its head out of the shell, then place back in the incubator giving it a rest and the time to see if it will push out on its own. About an hour or so.
If you do have to completely remove the chick from shell, place the chick in a small glass with a flat bottom covered in folded paper towel to rest and exercise its legs. the act of using its legs to push itself out of the shell is what sets the tendons in place, so we give it an artificial shell hoping it will let the chick do so on its own.
In the future, you can melt the crisco {make sure it is at room temp before using] or use olive oil and use a small tiny kids paint brush to brush it on the membrane, that way you never have to worry if you have used to much.
