Shrink wrapping rarely occurs with eggs in a nest. They are not the same type of conditions that exist inside an incubator. High air volume forced air incubators are the worst for causing shrink wrapping.Ok, hatching day for my first time broody turkey is tomorrow. One of the poults in the incubator already hatched and walking in the incubator (I had put eggs in the incubator the same day when I put eggs under the turkey). When I came back from work today the turkey was out of the nest having her dust bath. I checked the nest and one of the eggs had a nail size hole and the baby moving inside. I was concerned it will shrink-wrap as mama was outside of the coop and put the egg in the incubator. Mama is back in the nest now, but the weather is too cold to move The egg back in the nest.
