Why does the gosling have a big bag on its head?
A goose has a bag on its head, just like a duck has fins on its feet and a crown on its head. If we have to analyze it from the perspective of evolution, geese are better birds. It has a hard bag on its head, just like a helmet, which can effectively protect its head in battle.

The bag on the goose head is called sarcoma, which is found in both male and female geese. There are all China geese except Yili geese, because they are domesticated by Hongyan. Goose, as a common poultry, has a special life habit.

Bird [Goose], a clear subfamily of Ducks, is related to swans and ducks. Its forehead has an orange or dark brown fleshy protrusion, its mouth is slightly flat, its legs are of medium length, its body is bigger than that of a duck, and its neck is longer than that of a duck.

Living habits of geese:

1, cold tolerance

Adult geese have strong cold tolerance. They can swim in the water in the cold winter and spend the night outdoors. This is related to the thickness and compactness of goose down, which has a good heat insulation function. When combing the feathers, the goose beak will press the tail gland, and the extruded secretions will be coated on the surface of the feathers, making the feathers waterproof and cold-proof. The subcutaneous fat of the geese is thicker, which will enhance the cold resistance of the geese.

Step 2 be alert

Goose has keen hearing, strong alertness, quick response and loud cry. When it meets strangers or other animals, it will scream loudly as a warning. Some geese are aggressive and attack with their beaks and wings.

Therefore, in the brooding house, the male goose is often used as a warning to prevent other animals (such as mice and cats) from entering the house. However, in the process of feeding geese, it is necessary to avoid the geese from being frightened, so as to avoid stress reaction and affect the growth and fattening effect of geese.

3. regularity

There are fixed times for grazing, mating, eating, feather washing, resting and spawning. During grazing, activities such as grazing, swimming, mating, eating, resting and grazing all appear in a relatively stable cycle. Once this life law is formed, it will not be easily changed.
