The embryo stage exhibits a body mass of 12 to 18 grams and a body length of 3 to 4 centimeters, while the chick stage shows a body mass from 15 to 80 grams and a body length from 5 to 15 centimeters. Adult gray partridges have a body mass between 380 grams and 0.5 kilograms, and a body length of 28 to 32 centimeters.
Yaşayış mühiti

Çoxalma
The gray partridge reproduces with a reproductive interval of one year; in spring, the birds form pairs and the female constructs a nest on the ground, laying eggs. The female incubates the clutch, and both parents lead the young. Embryonic development lasts 3 weeks and 3 days. A clutch has 10 to 18 eggs, which constitutes the brood size. The young reach maturity from 10 months to 1 year and 1 month. The female produces 10 to 18 offspring.
