So what breeds can be feather-sexed?

[TerriLaChicks]

I've read that on day olds, two rows of equal feathers most likely is a male & uneven feathering a female, right?

But only on certain breeds----does anyone know WHAT breeds?
I'd like to try it & see how it goes on some eggs I'm incubating right now, if I have the right breeds...

They have to be bred for it. Fast feathering roo over slow feathering hens or visa versa.

There hasn't been much of a response. I figured there would be more replies by now.
