I'm pretty lucky *knocking on wood* My 2 boys rarely get scrapes, if they do from the pasture, its on their legs. When they are beating up on each other the scrapes are around their neck area. Dumas had a half-moon scrape that looked pretty nasty right between his eyes... I swear it looked like Twister nailed him with a hoof there.
Pretty much the owies are few and far between.
