A beak, where top and bottom beaks do not align properly, is called a cross, crooked or scissor beak, This deformity can be caused by genetics, an injury or the inability to maintain the beak’s length and shape by normal honing on rocks or other hard surfaces. It is also thought that an improper hand feeding technique and an unbalanced diet play a role in the development of this beak deformity.
