The woman knows what she's doing. The baby had been trying to hatch for a long time. It was pipping and part of the shell around it had come off a bit where it was thinner ( indication that the baby's beak was working on hatching. However, it had been too long and the baby's inactivity was showing that he was exhausted and didn't have much strengh left to come out.
She helped clearing the shell away from the beak and head. The water is warm to keep the baby's temp up and stimulate him. Rubbing him a bit too to get him to wiggle too. The warm water was also helping softening the shell.
Putting the baby's body in the water after hatching was to bring his temp up and again stimulate him, getting his blood going.
The drying process was so that he would again STAY warm as a wet baby will quickly get cold which is very dangerous.
The feeding was to rehydrate him as he had been struggling for a long time trying to hatch. Notice the use of a spoon to just put the liquid in his mouth and let him choose to feed as opposed to a syringe. Gave him a bit of strengh back.
She says at the beginning that it's an emergency situation only. I believe that she saved his life.
French is my mother tongue. Even though she is Canadian, I understood just fine
