What Causes an Overgrown Beak?
An overgrown beak can result from a developmental problem, nutritional deficiency, illness, or it can also be due to trauma or injury.
In these cases, the two different parts of the beak (the upper and lower) may start to miss each other, which becomes a problem as the area that is not connecting with the opposite beak then continues to grow. If this occurs, then beak correction is generally recommended.
