Helping a chick hatch

With 4 chicks hatched, mother hen Penguin left the nest yesterday to take the babies to the food and water. The last 2 eggs were abandoned. One had a pipped shell and chick peeping inside, so we took it to take a closer look. This egg, which was the largest of all of them, was pipped on the small end of the egg (the wrong end), which maybe was the problem. We brought it inside, but without a proper incubator set up, we decided to help it hatch.

In the photos you can see where we chipped off the shell without removing the membrane. We were trying to keep plenty of warmth and humidity -- and ended up pulling out the steamer pan! We used a washcloth and spray bottle to keep the membrane moist. Finally the chick hatched out of the membrane and we put it under its mother.
