That is the problem, no standard here in the United States. If we go by what the Europeans do, they prefer beards over wattles. I have seen too many pictures of bearded Brabanters and perhaps all the wattles I saw were the US version. If we are to go in the right direction, one will have to start doing something whether Brabanters should have wattles or not. That is why I had to contact a breeder who was from the Netherlands and the photographer that lives somewhere in the UK all have said bearded ones are preferred than the wattles and it would be points taken off when they exhibit a Brabanter rooster with wattles. So I say go figure!
If this breeder main objective to try to get bearded ones, then she is in the right direction, IMO and I would support in her endeavor in promoting this breed of having beards. 
Wished there is a few Brabanter UK breeders in here but none so far.
