White fuzz in roo's tail feathers?

[commosmart1]

My Welsummer too is over a year now and he started gettin a white patch of fuzz at the base of his tail feathers. What is going on? Thanks for help

I've seen some game roosters with that "accent" -I think it's a nice touch on those roosters. Flashy. Not sure if you want your Wellie to display it, though, if you are breeding him for type.

Could it be anything else? He is purebred
