I have an older rooster and hes missing some toenails, we got him as an adult so don't know how he lost them, has very dirty toenails and spurs and his tail feathers are kinda ripped up. They are a little tangled and muddy. So I was wondering how to get filth covered nails clean and if his tail feathers can be fixed or have to wait until he molts. Also, when you get scored for the showing do you get marked down if their missing toenails??
