If you're seeing discoloration or growth on the beak itself or Rj is acting ill (not wanting to eat or drink, trouble breathing or eating, listless behavior, etc) in addition to the change, it would be smart to have a vet take a look to rule out any issues such as a bacterial or fungal infection causing it. Some foods and pellets can also cause staining of the beak or feathers, so checking to see if any fruits or vegetables given match the discoloration may alert you to what is causing it so you can remove it and offer other items in addition to her regular diet.
