Lethargic female cockatiel
Our one year old female cockatiel seems as though she is very tired all the time and is not eating like she used to. She seems very miserable and her breathing is heavy. A few times a day she will go down to the bottom of her cage for 5 minutes or so but does not seem to be straining as if she wanted to lay an egg. What can this be and is there anything we can do to help?
