Popis: Studies were conducted on 2972 failed to hatch chicken eggs with embryonic deaths to detect the various abnormalities occurring during their development. The study included descriptive examination and comparison of unhatched eggs of chicken. Objective of the experiment was to study the occurrence of abnormalities of embryos at various stages of incubation in chicks by gross examination. Of the total eggs collected, a major contribution towards lesser hatchability was accounted by infertile eggs, followed by mortality during early period, late stage and then mid-stage mortality. A significant positive correlation existed between weight, length and width of eggs. Anomalies encountered in the present study were categorized as developmental failure, developmental arrest, developmental excess including twinning and atypical differentiation with skeletal abnormalities.
