Chickens are hatched in an artificial incubator. This is a device that mimics the conditions found under a brood hen. Temperatures of 100.5 F and humidity of +60%. Chicken need 21 days of these conditions to develop inside the egg. Of course, chickens are still hatched the old fashioned way, under a broody hen but only on small farms and breeder sites.
