As you can assume from the title, my budgie Celeste can't fly very well, and I don't understand why.
When she had just learned to fly (she was born in my house, I bred her parents), she was a good flyer, just like her siblings. She was able to fly for a long time and even to reach the ceiling while doing so.
But now when she files away from her cage (which is at a height of about five feet) she lands on the floor, and then not only she can't fly back to the cage from there, but she can't even fly on my bed (which is about one feet and a half tall).
How is it possible?
Celeste spent a lot of time in the cage for about a month, from when she was about two months old (when I gave away her siblings) to when she was about three months old (when I decided to separate her from her parents because her mother attacked her), as she used to bite me very hard and didn't want to interact with me.
After that month (between March and April 2019) she showed difficulty in flying.
Could the lack of practice during that month be the reason why she lost the ability to fly like she did before?
I took her to the vet last month, and she didn't find anything wrong with Celeste, except for her handicap (slip claws), so I don't think her difficulty in flying could be related to a disease.
Thanks in advance.
