Based on the analysis of the literature revealed that in poultry began a new phase - ovosexing. Today, there are more than ten methods of determining the sex of chicken embryos. However, so far not offered a single method that meets the requirements of cheapness, simplicity, minimal labour input, which do not require special expensive equipment and precision sexirani was the maximum. Listed criteria dictate the need for a comparative assessment of the efficiency of affordable and simple methods of sexual differentiation of embryos, in particular preincubation of sexing chick embryos by weight of eggs and visual evaluation of the sex glands. Comparing the effectiveness of these two methods, proven low interest rate mismatches of the obtained results, which allows the use of both methods independently. Despite a slight chance of having mismatches, to avoid errors in the experimental study, it is expedient these methods to use in the complex
