Sexing contradictions

[Freespin]

How accurate is DNA sexing? I once heard its not always 100% (which i find odd).
Anyway the reason i ask is because my partner owns a sulphur crested who was DNA a female but at 8yo her eyes are still dark. She also humps a lot, im not sure if that makes a difference, i know female dogs can get a bit humpy too haha. I do believe she is a SHE but i still wonder if there is any chance. She prefers males and is also a lot smaller than any male i have seen.

Do you think her eyes will eventually change or by this stage are they likely to just stay dark?

What type of lighting are you viewing her eyes from???? I find by bringing them into white light such as fluorescent lighting helps to view the correct color a lot easier. The color can differ from different types of lighting.

Not all females get red eyes, some stay dark. I think it's very very rare with a male with red eyes (if they even exist), but females with dark eyes do occur. DNA sexing isn't 100% because there's an extremely tiny chance the DNA sample gets compromised, I think it is. But you could always do another test and see if it's the same

(Female parrots preferring human males and male parrots preferring human females is a complete myth though)
