The gray partridge lays the largest clutch of eggs among all these. The grey partridge also known as the English partridge, Hungarian partridge, or hun, is a gamebird in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds. The grey partridge is a rotund bird, 28–32 cm (11–13 in) long, brown-backed, with grey flanks and chest.
The belly is white, usually marked with a large chestnut-brown horse-shoe mark in males, and also in many females. Hens lay up to twenty eggs in a ground nest. The nest is usually in the margin of a cereal field, most commonly winter wheat.
