In the first three months of life to define a sex of an Indo-duck quite difficult: for this purpose it is necessary to raise a tail of a bird and to make sure available or lack of a pseudo-penis which only experienced poultry breeders can consider often. However with age males and females find striking external traits on which they can be distinguished.
The main differences of Indo-ducks from drakes
If it is about adult individuals, for sex determination will be to look at a duck and a drake only enough: the male will be much larger than a female, and it will be evident at once. The average mass of an adult drake is about 5-6 kg while females at the same age weigh only 1.5-3 kg. At the same time males not only are larger, but also much massivny: they have a thick and long neck, a broad chest, powerful wings.Look also at the head of a bird. If you see the red rough skin coming for eyes, so before you a male. If skin more gentle, light pink is also located only between eyes and a beak, it is about a female. Ducks can also brag rather graceful, than a powerful bend of a neck. However plumage at them is much more modest: coloring of feathers of males, as a rule, brighter and more various, drakes have to attract with the look ducks.
How to distinguish a male of an Indo-duck from a female: additional cunningsMales and females of Indo-ducks differ not only externally. It is possible to define a sex of a bird even on a voice: ducks shout or "talk", making a sound "ук" or "ик" while males only hiss. Moreover, showing aggression, drakes not only publish loud hissing, but also raise a cop to look threateningly. Females simply are not able to do it. As the genital at little drakes of Indo-ducks has length only 1-2 mm and to make out it quite difficult, it is possible to use other option of sex determination of ducklings. First, at males the plumage is several tones more dark, than at females, and it can be noticed if to put several ducklings of a both sexes row. Secondly, drakes very quickly become aggressive: in 1-2 weeks after the birth they begin to fight with other ducklings and also with chickens if they grow with them together. Young males often offend birds with whom grow even if it is about larger individuals. Females, on the contrary, behave more quietly, do not start fights and will hide in a corner rather or will escape, than will accept battle. There is one more interesting difference between females and males, and it is in features of behavior. As a rule, drakes always pass Indo-ducks forward, and move slightly behind. It concerns both walk by land, and swimmings, and even flights. The exception is made only by a situation when the duck hatches out eggs, and drakes, having been left without the females, walk small groups, serially passing each other forward.
