I accidentally twisted off my roo's entire outer spur while trying to trim it. The little soft spur nerve thing is intact but it's raw and soft. The tip of it is blood red and the hens are relentlessly picking at it. I put on blue coat and pick-no-more, but the little bit of blood slowly seeps through, and the hens notice immediately. How long will it take for this soft internal spur to harden up and lose that blood red color? Thanks!
