The title says it all!

How accurate IS feather sexing? I have heard that it is fairly reliable but want to know what you all think...

IMO, it only works on breeds bred to be feather sexed.

Ok... What breeds are bred to be feather sexed?

Do you happen to know what the breeds considered "slow feathering" and "fast feathering" are? I saw a hatchery video that was selling purebred chicks but they were feather sexing...
