Bonnet affirms that, before fecundation, the hen's egg contains an excessively minute but complete chick; and that fecundation and incubation simply cause this germ to absorb nutritious matters, which are deposited in the interstices of the elementary structures of which the miniature chick, or germ, is made up.

The female is concerned with the complete reproductive process, which may be divided into four stages. These are copulation, fecundation, gestation and parturition.
