Hi, I got a new cockatiel, and it has become apparent that he /she doesn't preen his/her tail. It's moderately dirty. The rest of the body is preened nicely, it's just the tail.
I gave her/him a bath, to try to induce preening the moist feathers, but it didn't work.
Can anyone explain this, and provide some tips on how I can teach this behavior?
Thank you!
