How can a budgerigar just bought from Taobao tell whether it is healthy or not? What preparations do you need to make when you get home? Please explain it carefully, it's my first time to raise it ~ ~

First, observe whether there is feces and vomit on the hair, whether the wings droop, whether the head can be lifted, whether the hair is blown up, whether there is mucus and redness in the corner of the eye, whether there is white powder on the nose, whether there is foreign body in the corner of the mouth, whether the abdominal hair is complete, whether it can be eaten and excreted normally, and whether the feces are normal.

Second, parrots who have just arrived home are unfamiliar with the environment and should not be frightened. It is best to put it in a dark environment, keep quiet and give enough food. Pay attention to whether parrots have night terrors these days. After two days, you will be familiar with it and you can raise it normally. Budgerigars usually eat millet and drink cold boiled water. Recipes can be more complicated. You can't feed oily feed in summer, but in autumn and winter. If you are weak, you can feed water with half a spoonful of glucose. I usually come three times a week. It's normal for the tail to tremble and not sing, because you will be afraid if you are not familiar with the environment.
