	This is what is commonly referred to as a "snail scur". The term "snail scur" goes back at least into the 1800's, indicating that heterozygous polled rams have been recognized in sheep for quite a while.   Snail scurs must be monitored by the shepherd, as they can curl into the flesh. Those should be trimmed if the ram is going to be kept. The scurs commonly break off, and some do not grow back.   Despite some opinion, a snail scurred ram is perfectly acceptable to be used for breeding. It is a MYTH, with NO basis in fact, that only a smooth polled ram should be used in a polled breeding program. Dr. S. Dolling encouraged their use as recently as 2004.    These snail scurred rams are Pp, and have a valuable poll gene to pass down.
