The care below is rhea-level guidance from our species hub, sourced to Animal Diversity Web — Greater Rhea and Merck Veterinary Manual — Ratites (Ostrich, Emu, Rhea).

How long do Rheas live?
Rheas commonly live 10-15 years in the wild-type managed setting, occasionally up to 30 years in captivity with expert care.
What do Rheas eat?
Feed a ratite or gamebird diet of formulated pellets, grass, hay, and grains, plus controlled protein; avoid avocado and chocolate, and limit high-iron items. They forage on vegetation and need grit. Fresh water must always be available; overfeeding protein harms growing chicks.
