Vitamin A deficiency has caused a cheesy white mass to form in the corner of the eye, which is probably a secondary infection after break down of the epithelium around the eye. Deficiency of vitamin A also impairs the ability to withstand infection and reduces the immune system's response to challenge. There is often a watery discharge from the eyes, conjunctivitis, and the eyelids may be stuck together. Prolonged deficiency causes anorexia, completely stops growth, the bird becomes emaciated, weak, lacks coordination and has ruffled feathers.
