First of all, the cost of raising geese is high. In ancient times, our ancestors summed up the saying that "the family has ten thousand tons of grain and doesn't want to raise a king with a flat mouth", in which the "king with a flat mouth" refers to geese. This proverb means that even if there are 10 thousand tons of surplus grain at home, we don't want to keep geese because they eat a lot. It's true. Goose is much bigger than chickens and ducks and eats more. Like chickens and ducks raised by farmers, they just need to give them some leftovers to eat, and then they will go to the wild to find some vegetables and insects to use. However, although geese are also herbivorous waterfowl, they eat a lot. In the words of the old farmer, "raising geese is like raising pigs", and a goose eats almost a catty of vegetables a day. And the growth cycle of geese is also relatively long. For example, chickens in some farms are released in more than a month, but it takes about 4-5 months to raise geese for sale. Long cycle, high cost and higher risk.
Secondly, the egg production of geese is very low. Many farmers like to raise chickens, because chickens are easy to breed and don't eat much, but they lay a lot of eggs. But geese are different. This kind of poultry is very delicate. It is too hot to lay eggs, and it is too cold to lay eggs. It lays eggs intermittently in spring and autumn every year. Most geese lay about 50 eggs a year, and even some high-yield varieties produce no more than 100 goose eggs a year. It is also because there are many chickens and the egg production is high, while the egg production rate of geese is very low, so things are rare, so goose eggs are much more expensive than eggs. It is also because the laying rate of geese is low, which is also a reason why farmers are unwilling to raise geese.
Finally, geese are not as good as chickens and ducks. Although geese are poultry like chickens and ducks, the requirements for the growth environment of geese are relatively strict. Generally, geese can only be raised near the water source, otherwise the mortality rate of geese will be higher. Compared with chickens and ducks, raising geese requires higher technology. Moreover, geese also have a big feature, that is, they are aggressive.
