You should not have to help chicks hatch ever. I just hatched 18 eggs from first time layers and every egg hatched on its own. These were their very first eggs and against my better judgment, but I decided to set them. They had no problems hatching on their own and shouldn't if the incubation settings are appropriate and the bator is not opened at hatch time.
As I read this post more, I am thinking opening the bator 3 times a day is your problem and will hinder a successful hatch. I'm sorry you're having these troubles and hope some more chicks hatch ok for you.
