Thanks. I wasn't really talking about wings - That I really do understand. The tail I wasn't thinking a feather that would affect the shape or look. Not a Houdan, but this boy I have here went to show. I did not pull his lone tail feather out, but it feel out itself before show. He is getting his big boy feathers. That tail feather looked weird, and I think he looks far better with the random feather out, but that's me.If you pull out s scraggly feather in the tail or wing or on the hocks it s very noticeable that a feather is missing. Watch a judge at a show, they will spread the tail and wings, missing feathers are noticed and this in itself is detrimental to the show quality of that bird. Pulling an off colored feather of the back or stubs on the feet is not noticed on inspection of the bird. So, pulling that scraggly feather out of a tail whether it is cheating or not will downgrade your bird anyway so you really don't gain much.
