hi, if its just a scurl which has come off, its no big deal. I would put something on it, either antibiotic or blue spray like little blue suggests, or some veterinary wound powder. If you don't have either, and its bleeding, put on cornflour, which is great for stopping bleeding in an emergency. A scurl grows sometimes after a goat has been dehorned. If its just a wee one, chances are it'll get knocked off every so often. Beth
