Sebastopol Geese
Adult birds, ready to breed.
Sebastopol geese are commonly cited as living 15 to 25 years, with well kept birds regularly reaching the upper end of that range. They are a long-lived animal by poultry standards, closer to a dog or a parrot in commitment than to a chicken.
Published figures for domestic geese generally sit between 15 and 25 years, and Sebastopols are usually quoted in the same band. Individual birds vary widely, and the figure most often reported by keepers is somewhere around the middle of it. Treat any single number you see online with suspicion, including this one.
The practical point is the commitment. A gosling bought this year may still be with you in two decades. That is a longer horizon than most people expect from poultry, and it is worth sitting with before ordering.
Predation is the biggest single cause of loss, and it is the one most within your control. Sebastopols cannot fly, which makes fencing easy but also means they cannot escape a threat the way another bird could. Secure housing at night is not optional.
After that: leg and joint problems from poor early nutrition, injury from badly designed water access, and the ordinary consequences of wet birds with no dry shelter. All three are covered in the care guide, and all three are avoidable.
Commonly cited at 15 to 25 years, with well kept birds regularly reaching the upper end. They are long-lived by poultry standards.
Thinking about the commitment? The care guide covers what those years actually ask of you, the FAQ covers cost and temperament, and breed facts covers origin and rarity.
