Fertilization: Sperm Penetrates Egg. It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete, including whether it's a boy or girl.
The shell is created by calcium deposition around the forming egg within the uterus. The fertilized ova takes approximately 4 hours to travel to the uterus. Once in the uterus, calcification of the egg's shell takes approximately 20 hours. This is why a hen can only lay one egg per 24 hour period. About 15 minutes after the first egg is laid, the hen ovulates again and the process is repeated.
