Abstract: The experiment was done at the local breeding farm of the Hibrid Center of Poultry Breeding - Stara Zagora. Turkey hens from the lines: Meat Heavy (MH)turkey, Layer Light (LL)turkey, North Caucasian Bronze (NCB) were used. From each line of turkeys was tooken 10 prcennt of the daily output of the eggs in three consecutive days at the middle of the productive period (for month April). Measuring the length and the width, was done on the eggs with a gauge with a punctuality until 0.05 millimeters. The index was decided under the formula: If (percent) = d / D x 100. Each egg was weighed and measured. It did not has dependence between the index of the form of their fertility. Most short fertility 78.26 percent had the eggs with the index of the form between 74.01 and 76.00 of the Layer Light (LL)turkey. The eggs from the NCB turkeys with the index of the form over 76 - 95.83 percent had highest percent of fertility. The highest percent of hatch of the three explored line-turkeys had the eggs with an index of the form between 74.01 in 76.00.
The index of the form was in negative and low correlation with the weight eggs.
