If hatching naturally, the mother hen will sit on the eggs to maintain the optimum temperature so they can develop until it is almost hatching time.
Sometimes hens will not take to sitting on their 14
eggs, and so a farmer may need to purchase an incubator and do this step him/herself.
The chick inside the egg will generally grow for 21
days, using the egg yolk as a means of nutrition as it grows. Along with sitting on the eggs, the hen will also use her beak to turn them to aid their development.
