CARS do you have pictures of your houdan to post?
Here is what I like/dislike about my houdan according to the standard you have posted. My hens are too small and have too much white mottling on them, their crests are not full enough and their breasts not big enough, they are too small overall, although one is slightly larger than the other.
As for my roo, I am more pleased with him. He is darker, does not have a lot of white in the tail, has the small wattles, comb and feet that he should have. His beard is not full enough, his crest is not round enough. He is a decent size but could also use more breast as well. Of course, his color needs a lot of work.
