Nankins - Critcally Endangered?

[scribbleuk]

Hi,

I'm lucky enough to have a small flock of Nankins. I was doing some research on them and noticed a number of sites refer to them as on the "critically endangered list" or "registered as critically endangered". Any idea where this endangered list actually is? I've searched several nature sites and didn't find Nankins listed in any of them.

Thank.

Not sure where the list s, but they ARE critically endangered, they are extremely difficult to find for sale.
