|q2= What is the significance?

|a2= The major significance of achromatosis is as a serious sign of an underlying nutritional deficiency. Unlike signs of some other deficiencies, it is not dependent on the severity of the deficiency except in extreme cases where the feathers may not grow at all.

|q3= What treatments are needed to return feathers to their normal colour?

|a3= The proper course of action is to supply the limiting nutrient and, if the bird is still growing, observe growing feathers for normal pigmentation.

When growth is complete, a reduction in nutrient requirements occurs. This reduction in requirements may allow a diet inadequate for growth to serve as an adequate maintenance diet, allowing the bird to produce normal feather colours. In this case no treatment is required.
