Breeding Research indicates that grouping a single male with two or three females will generally give high fertility. When quail are kept in colony pens, one male to three females is sufficient and reduces fighting among males. Pair matings in individual cages also give good fertility. Fertility decreases markedly in older birds. Avoid mating closely related individuals, because inbreeding increases the incidence of abnormalities and can greatly reduce reproductive performance. For this reason, it is desirable to record hen numbers on the eggs, incubate them in groups, and permanently mark the chicks at hatch time.
Pedigree records can be kept by using commercially available wing bands or leg bands to identify quail of all ages. Quails can be identified temporarily by a little oil paint on the back feathers (not on the skin) or fingernail polish on the toes.
