ABSTRACT
Japanese quail (Coturnix Coturnix japonica ) has widely distributed in various parts of the world. Japanese quail has been used as a good source for egg and meat, it has been also used in many areas of biological research.
It grows rapidly to maturity , the Coturnix quail matures sexually of six weeks after hatching (Wilbor and Wilson 1972), its mating activity was at its maximum between 70 and 210 days of age (Sefton A.E and Siegel,1973) . It has short incubation period and high rate of lay ,the quail may lay more than 300 eggs in their first year of production (Wilbor et al 1961). Its small size (150g at maturity) permits the storage of large numbers of birds in a relatively small space , consumes less feed in the adult stages which is much less than that of the chicken . Shortly , it is very economical bird as an experimental . bird or as commercial producing bird .
Obtaining a high production and reproduction performance in Japanese quail requires some collective factors work at it 's best . Behavioral factors are the most factors control bird to life and its welfare. Stocking density (space allowed for bird to live) even in cages or floor pens , mating ratio (male to female ratio) in the flock and type of housing are some of the most important elements of the managerial factor that control the production and reproduction performance of quail breeding flock (Narahari et al. 1988) .
