My friend has a yearling colt (which i may be acquiring) It is 13 months. She has said that he has not 'dropped' yet which obvouisly will mean i wouldn't be able to have him gelded yet? What is the latest a colt will 'drop' and does it mean he will have a problem if he doesn't 'drop' soon? I take it he would in fact be fine to go out with mares until he 'dropd'? shows no sign of colt behaviour
