Introduction of Japanese quail

Introduction Japanese quail are hardy birds that thrive in small cages and are inexpensive to keep. They are affected by common poultry diseases but are fairly disease resistant. Japanese quail mature in about 6 weeks and are usually in full egg production by 50 days of age. With proper care, hens should lay 200 eggs in their first year of lay. Life expectancy is only 2 to 2½ years.

Japanese Quails – Male and Female

The females are characterised by light tan feathers with black speckling on the throat and upper breast. The males have rusty brown throat and breast feathers. Males also have a cloacal gland, a bulbous structure on the upper edge of the vent that secretes a white, foamy material. This unique gland can be used to assess the reproductive fitness of the males.

Sexing of Japanese Quail

Its fairly easy to tell the difference between male and female quails. The colour markings and body size generally give it away. We’ll look at the Coturnix also known as Japanese or Pharaoh quail. The male has a distinct rusty, reddish chest. The female has a white chest with mottled black. Females are generally heavier with a broader chest, males are slim in appearance. Males also have a distinct call, and are often running around attempting to mate with females which lay the eggs.

Body Weight of Japanese Quails

If the birds have not been subjected to genetic selection for bodyweight, the adult male quail will weigh about 100–140 g, while the females are slightly heavier, weighing from 120–160 g.

Japanese Quails Eggs

Japanese quail eggs are a mottled brown colour and are often covered with a light blue, chalky material. Each hen appears to lay eggs with a characteristic shell pattern or colour. Some strains lay only white eggs. The average egg weighs about 10 g, about 8% of the bodyweight of the quail hen. Young chicks weigh 6–7 g when hatched and are brownish with yellow stripes. The shells are fragile, so handle with care.
