Where can I get different/ rare Cochin colors?

[Sylverfly]

So I am looking for a few Cochin colors (hatching eggs). I'm really looking for Standard sized Cochin. If anyone knows or breeds please respond on this thread thanks. I'll list the colors I already have below, I'm looking for any colors I don't have. I would really like to buy a combination of different colors since I have (and need to maintain) a relatively small flock. I hope this is OK to post this here I didn't want to make a want add because I'm still "looking" and not sure what I "want" yet I guess, lol.

Cochin (colors) I have:

STD:
White
Black
Buff
Blue
Red
Barred
Partridge
Gold Laced
Silver Laced
