Maybe because this bird is considered “rare”? It is on the watch list as far as conservatory. Not a lot of hatcheries have them. I have two females and love them. They are clowns and very docile.
The 'A' in Faverolles is a soft 'a' or short 'a' like apple - the 'O' is long not short, the 'S' is silent - EVEN when it's plural - It's a French thing. If you're going to judge the breed you should probably know how to pronounce it.
