The short answer for a scarlet-chested parrot
An adult scarlet-chested parrot usually needs two small measured servings a day, one in the morning and one in the late afternoon. A scarlet-chested parrot, one of Australia's grass parrots, is a slim, ground-leaning feeder that does well on a controlled ration rather than a permanently full seed dish. The morning serving can stay down for grazing, while the second serving, measured against what remains, tells you precisely how much this dainty species actually consumed.
Why restraint suits a grass parrot
A scarlet-chested parrot spends much of its wild day walking through low cover picking at grass seeds, taking small amounts over many hours and staying close to shelter. In a cage or planted aviary the bird keeps the ground-feeding habit but covers far less distance, and rich seed mixes designed for bigger parrots deliver more energy than it spends. Fat builds quietly on a grass parrot, and a bird that looks merely plump may already be carrying weight that strains its health. Two modest servings keep the grazing pattern the species expects while putting a ceiling on the total, which is the balance this particular parrot needs.
Composing the two servings
The morning serving for an adult scarlet-chested parrot should be a measured amount of a fine grass-parrot seed mix, millet sprays as an occasional portion rather than a fixture, and a small offering of leafy greens or seeding grasses if you can supply them, laid low or on a ground tray where this species is comfortable feeding. The late-afternoon serving repeats a smaller measure of the base mix and fresh greens, replacing anything soiled. Hold back on sunflower and other oil-rich seeds as everyday items; for a scarlet-chested parrot they work better as rare training rewards than as bowl contents. Fresh water at both servings is essential, and because these birds feed and drink low, dishes placed near the floor need checking for contamination more often than a parrot's raised cups.
Ground feeding, calm and company
Scarlet-chested parrots are gentle, quiet birds that stress easily around boisterous cage mates, and a nervous bird may under-eat even when the serving count is right. Feed this species where it can reach the ground tray undisturbed, and if it shares an aviary, put out a second feeding station so the scarlet-chested parrot is not displaced by pushier species. Keep serving times calm and predictable; sudden changes of dish position can put a shy grass parrot off its food for a day. A small scatter of the morning ration through clean grass or a forage tray encourages the walking-and-picking behaviour that keeps this species active between servings.
Watching condition in a slim species
Judge a scarlet-chested parrot by gentle feel and behaviour rather than looks alone: the keel should be lightly padded, the bird should come down to feed promptly at servings, and droppings should stay consistent. A grass parrot that stops ground feeding, sits fluffed in cover, or shows a sudden drop in droppings needs an avian veterinarian quickly, because small quiet species can fade fast once they stop eating. Equally, steadily rising leftovers of the fatty seeds alongside a rounder outline suggest trimming the mix, not the meal count.
