Uhhh..
Not that great...
I'll show you decent the more decent one first.
It's got no white down really that I can tell. It's pretty light gray under chest and rear tho. Some white toe nails that I can see. While it was peeping I saw it has a light grayish pink tongue with darker mouth. Just trying to see what I can see through the plastic bator sides.
And this one..
I have no idea what it actually is but it's supposed to be Cemani..
So.. yeah. You get what you pay for.
But I do think the second one is cute!
First one doesn't look bad at all, from what I can see and your description... second is definitely not a Cemani... Australorp maybe?
