Scarlet-chested parrots are also vulnerable to "Candida" infections in aviculture. Since they are prone to "Candida" infections, this is best addressed in their diet. Remove everything from their diet that encourages fungal growth, like refined flour (most commercial egg foods are flour-based) and sugar (most ripe fruits). Add as many natural antifungals to their diet as you can. Fresh crushed garlic is an excellent antifungal. Also herbs like oregano, thyme and rosemary. With proper husbandry and a more natural approach to their diet, Scarlet-chested parakeets prove to be hardy and long-lived.
