First, I found it in my friend's local chicken breeds.
I am love lavender too much, so I think it is.

So my friend sent it to me by express from Beijing, about 2000km away. It almost became food.
After it arrived here, I carefully observed that there were few black spots on it.

Then I tried to combine it with the Polish chicken. Because it is also crested.

Then, when I arrived at F1, I found that it was actually a dominant gene, so it was not lavender.

However, when I suspected that it was a blue gene, it did'nt appear any dark colored chickens, but half of them were the same light color as its mother.The other half is black.
Then, I continue to use WCB polish male cross the F2.

This color still appears in F2.

The following are all F2:

Until recently, I also found that their tails were white, which made me wonder, what gene is this?

@nicalandia, are these the result of Smokey?
It's not smokey. Smokey its much darker when homozygous.

This is what I believe.

This is clearly dominant(50% of the progeny inherits that phenotype). Looking at the Original hen and the following progeny I believe it's yet another Allelic mutation of dominant white.

i+(wildtype
I (Dominant White)
I^d(Dun)
I^S(Smokey)

I would officially call this True Platinum and asign the unofficial nomenclature I^P

It's a Beautiful Color but two copies of those will result on a Fully white bird(Homozygous).
 
Thank you for your answer. Has this ever appeared on other breeds?

I didn't think of platinum.
 
I would guess a shade of blue
Light Blue when crossed to solid black tend to get darker and not lighter.. I see an even shade on the first female and consecutive back cross to Polish.

Blue Polish Rooster for reference

Blue has difficult in diluting the Hackle, Saddle and some tail feathers on Extended Black males.
