After peeling away at the shell trying to help the chick hatch, the momma moved the egg out of the nest. When I found it, it was getting cold and had not broken through the white membrane. Very carefully I peeled away tiny bits. It bled in two spots and at the point I covered the membrane in a warm, damp paper towel until it was ready. If you must help one, stop right away if you see blood and wait a bit. It's important not to let the membrane dry out. Also, it's important for the chick to get an air hole at the beak. I don't recommend helping, but there is no way this chick would have broken loose from the shell. This process took about two hours. Once the chick was dry and rested under a heat lamp, I returned him to his momma. He's doing well.
