I was never told how stressful hatching chicks was, the first time I used an incubator we had a power cut overnight half way through the incubation period, I thought all 20 eggs were a gonna, but 3 hatched with only 1 surviving and she is still with me nearly 6 years later. I think she is a bit "special" but still fighting fit. From that point on, I have been amazed by how strong those little chicks can be.
