Those who work in hatcheries will find the introductory notes on egg formation in the hen, nest management, egg collection, fumigation and cooling of eggs, early embryonic development and male fertility informative. This should lead to a better understanding of the role of the breeder farms in maintaining hatchability.

A discussion on effect of transport of eggs to the hatchery, the selection of suitable hatching eggs, and the correct handling and storage procedures follows. The effect of storage period and conditions such as temperature and relative humidity on hatchability is discussed.

Practical work: Dissection of male and female breeder birds and identification of the functions of the reproductive organs and differences between fertile and infertile eggs at oviposition will be identified.
