You might find the occasional baby swan at your grocery store or pet store, but experts advise against buying one for several reasons. First of all, many of these baby swans come from an irresponsible breeder who is just trying to make money--so these babies often come from overpopulated parents. Secondly, it’s nearly impossible to know how old the baby is when you buy it; if they’re too young, they won’t survive in your care. Finally, even if you can provide the right care for your new pet bird and he survives, he will never be fully domesticated and will stay wild with a mind of its own. All in all, these are good reasons why most experts recommend against buying a pet swan.
