I have tried every recommended method. I have found no benefit to letting them rest or not turning them. Now if I was to hatch shipped eggs, I would allow them to warm up and then put them in the incubator and start turning them. My incubator turns them once every three hours so they are in the incubator for three hours before they actually start turning.
There are studies which show that turning the eggs is more important in the earliest stages of incubation than at any other time.
I understand how turning is more important earlier than later because the chick is moving itself inside the shell enough later. But i thought settling the eggs after shipping was beneficial because of letting any loose air cell try to stabalize? Ive only hatched shipped eggs three times and attempted it four times. I continue to avoid it at all costs especially after getting a complete bust on highly anticipated turkey project eggs from my friend walnuthill.
