We tried to hatch an egg from an incubator, which has not hatched any egg before. It turned out that the success of hatching an egg does not depend on whether the incubator is brand-new or not. The ingredients of the egg determine its own fate. A healthy combination of ingredients will most likely result in a successful hatch. It is natural selection in a miniature scale.
All these understandings, however, would not prepare you when you learned that you got a blighted egg in the incubator. And it was suggested that the blighted egg should be removed and the interior of the incubator should be thoroughly cleaned. Therefore, it will be ready for the next incubation.
Only time will tell if we could recover from this loss and try again.
