What should the parrot do if it catches a cold?
Parrots eat fruits, vegetables and cereals, so it is recommended to feed them yellow rice (if they don't shell, the parrot will shell itself, and the quality of shelling is not good), and the market price is 2 yuan/kg. Cooperate with feeding some apples or something, take a bite of whatever you eat, not too much.
Change the water frequently, because birds like to defecate in the water, which breeds a lot of bacteria, and parrots will get sick after drinking it.
Note: When a parrot drinks water, the water may enter the nasal cavity. It will sneeze and spit out the water. This is not a cold. Don't feed the parrot cold medicine, it will kill the parrot. My Feng Xuan parrot also has a runny nose. My dad said it was because it was cold outside these days. Get a sweater or something outside the birdcage, and then cut some holes with scissors to breathe. It will be fine in a few days. This is my Feng Xuan "Xiao Xuan". It will be fine in a few days. I am very happy. I don't know if my method is useful for your luck, but I can try.
