Three types of hatching eggs during the period of their stay in the nest - a relatively continuous, intermittent and combined. For all types of incubation in egg-laying period in the development of the embryos move, being at different stages by the end of lay. The rate of development of embryos increases with the accumulation of eggs in the nest. Different domestic partner of the same species in the same breeding season at the same site is not the same type of brooding efficiency. The value of age difference in the embryos of more renewable clutches than basic. Depending on the type of environmental conditions in the incubation period of egg laying may change as the value of age difference embryos.
