Now, look at this video. A female tiel with a super overgrown beak goes to the vet and he says NOTHING about liver disease, supplements to help her, nothing! On top of that, he gives completely wrong information like saying that 'trimming a bird's beak is something that you would do once in a lifetime' - WRONG! Healthy birds never need a beak trim!
