That is also what some breeders are doing in some countries. The introduction of Russian bred Black Coppers, after the Germans had eaten nearly all French poultry in World War 2, was a disaster for egg colour. It took many years to eliminate the problem.
White feathers can be genetic in origin, or due to a damaged feather follicle. A plucked white feather often re grows the correct colour; or appears after a moult where there were previously none.
In my personal experience, from experiments I have done in the inheritance of the dark brown egg colour, it has taken at least 5 to 6 generations back crossed to the original breed (Marans) to obtain the required colour.
Re the "cotton tail" this is a common fault in most breeds. Mostly due to hormonal levels in the males, part of normal morphology. As I said Standards describe the IDEAL or Perfect bird which is not necessarily achievable. I personally would not be over concerned about it.

Hi David,
5 to 6 generations in chicken years isn't very long IMO. The solution is to gather together 6-12+ dedicated breeders to work together to eliminate defects, cotton tail or short toes for example. Which requires a willingness to exchange eggs, chicks or mature birds.
So what do we give roosters to lower their hormonal levels
