What should be noted when domesticating graylag geese?

Graylag geese are fierce by nature and afraid of people, maintaining a high level of vigilance toward humans, and in open spaces they usually keep a distance of over 100 m from people. When caught and bound by people, they will struggle and resist with all their might, refuse to eat or drink, and soon die. To get through this stage, the poultry-luring method can be adopted.
Poultry are animals domesticated by humans, such as chickens, ducks, and geese, and they will respond to human calls when being fed. Put the graylag geese together with poultry (a cage should be added or the graylag geese should have their wings clipped), so that the graylag geese are not too lonely. When the poultry are called, the poultry come crowding over, letting the graylag geese see the friendly relationship between their own kind and humans, thereby gradually dispelling their fear of humans and making their temperament gradually gentler. On the other hand, when the poultry scramble for food, it can also induce them to eat. This stage is very important and is the key to the success or failure of raising graylag geese in captivity.
In this critical process, the following points should also be noted:
1 If raised in cages, the cage must be sturdy; if raised in pens, the pen walls must not be made of stone or bricks, so as to prevent the graylag geese from becoming frantic in the early stage, breaking through the cage or dying from colliding with the walls.
2 If raised together with poultry, the number of poultry must not be too large or too small. If too large, because of their exclusion behavior, the graylag geese will be attacked by the flock of poultry and become uneasy; if too small, the density of attacks by the graylag geese on the poultry will increase, which may cause the poultry to become restless and uneasy. But one thing should be understood: compared with poultry, although geese have larger bodies, broader bills, and powerful wings, and appear fierce when attacking, in fact the graylag goose's bill is not as strong as a chicken's and its claws are not as strong as an eagle's, and it will not kill the poultry.
