A question that I often get is “How do I sex my quails?”
The easiest is that the male quails crow and the females do not. Should your quails be well housed and fed, the males will start crowing at about 3 weeks of age. I catch the crowing males and place them in a different brooder and come the time that they can go out to the breeding cages, or be sold, at 6 – 7 weeks of age, they are all sexed. Mature male quails only crow when sexually active during the breeding season and not so much when molting and not producing. Secondly the Pharoah colour and Italian colour can be feather sexed in that the males have brown feathers on the chest where the females have black spotted chests. The problem comes with the Tibetan colour and White colour where you cannot feather sex them as males and females look alike. All birds can be vent sexed though. The cloaca opening in the female is larger and more plump. In the males the cloaca opening is more tight and they also have a red swollen gland on the top end of the cloaca opening and when pressed a white substance appears, which is lubricant and not semen. The females do not have this gland. This gland in the males is also very depressed when not in the breeding cycle and it is more difficult to distinguish then.
