@weko you will be a great parrot owner
Don’t you worry about that. Your bird will love you
as others have said, let the blood work be done. It can tell you about diseases your bird may have. A sick bird will never show it untill it is too late. Because parrots in the wild are prey animals, they will hide any sickness. Doing the bloodwork can tell you a lot about the health of your macaw. And ofcourse at the same time about the DNA, catch everything in one visit
Your bird will not be harmed by it, and she will not hate you for it, don’t worry
But you WILL gain important information that we otherwise may never know, untill its too late
