How do you know when a parakeet is sick?
Laying down in a strange position is a good sign of sickness. Otherwise, if their poo looks exceedingly different and is more regular than usual, that can also be a sign.
losing feathers, stops chirping, shivering, fluttering wings and falling from their perch are signs they are sick, and if they stop eating or drinking.
The beak turns purple. Hope this helps :)
