The peculiarities of changes in the linear size and weight of ovaries of oviparous hens at different physiological stages of postnatal ontogenesis have been studied. The absolute indicator of the linear size and weight of the egg of hens is characterized by an intensive increase from the first 15 days of postnatal ontogenesis to 35 days, as well as the duration of this condition up to 120 days, physiological maturity, that the highest at 168 days, a decrease in this indicator to 570 days due to the stage of generative extinction of ovarian function at the stages after 168 days, morphometrically established that the coefficient of increase in indicators is higher in weight compared with linear dimensions in the period from 15 to 570 days of postnatal ontogenesis. It was also established that the cytoplasm of the oocyte is homogeneous, weakly basophilic, the nucleus is somewhat shifted to the periphery, the chromatin is in a dispersed state, and the nucleolus is clearly visible in the nucleus. Follicular epithelium is single-layer squamous. The nuclei of epithelial cells are hyperchromatic, flattened, the cytoplasm is weakly basophilic. Around the follicle lies loose connective tissue, the main cellular elements of which are fibroblasts.
