Abstract
The research of hatching of immature born birds of 27 species showed that its length on inter species level does not depend upon the size of clutch, but is determined by the mass 0-day hatchlings and definite size of birds. Changeability inside species of the hatching length depends on the type of laying eggs, individual features of hatching during the nesting period, size of clutch. Phenotypical heterogeneity of nestling in broods at the end of the hatching in addition to its length is determined by the size of nestling and adult birds, size of brood, behavior of parents, weather and feeding conditions.
