I have never seen fowl pox on the feet. Normally, it's on the comb and face area. If they survive fowl pox, which most do, they become immune to it and will never get it again. I have vaccinated for fowl pox in the past, but did not do it this year.
You can put a drop of Tylan50 (undiluted) directly into the eye.
