The difference between a gander and a goose.

Poultry breeders know firsthand how difficult it is at times to determine the sex of certain species. If, for example, it is not a problem to distinguish a chicken from a rooster even at an early age, then the gander and the goose look very similar even at a mature age. But the further breeding of this bird, as well as the cost of an individual on the market, depends on the correctness of the definition, which plays an important role for breeders. If you are concerned about the problem of sex determination in poultry, we suggest that you familiarize yourself with some ways to determine the sex of geese.

Distinctive features


Like many species of animals, geese differ from females in size... In this type of poultry, the geese are much larger, the weight of an adult goose is from 6 to 9 kg, and that of a goose is from 5 kg. In addition, the neck of the goose is somewhat longer and the head is larger than that of the females. Unfortunately, sex determination in birds in this way is unreliable, since you still need to know well the characteristics of a certain breed.

Some breeders of these birds pay attention to their habits.

Habits and character

The bullying geese entered into many sayings and proverbs. Most often, an obnoxious character manifests itself during sexual activity, when the males fight for the right to cover the females. Geese, on the other hand, rarely enter the warpath. Therefore, if someone in the herd is bullying, then most likely it is a male. By the way, if you pay attention to the herd that goes to the water, the leader goose is the first, the females meekly follow him.

Males have a loud, hoarse voice, while females cry long and loudly. In the water, the ganders stretch their necks up, and the geese horizontally, the movement of the neck in this case is similar to bows. In addition, even young geese like to sit more, and geese are more likely to stand.

But all these tips by definition do not always work.

Determination empirically

One of the most reliable methods (but it requires some skill and dexterity) is to determine if a goose has a penis. To do this, you need to know exactly its location. The anatomical structure of the goose is such that the penis can be noticed only when the cloaca is opened. To do this, you need to turn the individual onto its back, clamp the head in such a way that the bird does not resist, but gently, so as not to injure, move the cloaca apart. If, upon examination, a spiral curl is noticeable (this is the genital organ), then a male is in front of you.


  1. As a rule, males are larger than females, but this is noticeable only at puberty.
  2. Geese are cocky, often climb into a friend, geese behave more calmly.
  3. The geese have a rough, hoarse voice, the females cackle long and loudly.
  4. The goose always goes first in the herd, the females behind him.
  5. In the water, geese stretch their necks up, and geese horizontally, making bow movements with their neck.
  6. The geese are sitting more, and the geese are standing.
  7. In the cloaca, the male has a genital organ in the form of a curl, while the females do not have it.
