Help, have a steer, 1 1/2 year old, to go to fair. Have what I think is a wart about 2 to 3 inches below his eye. The size is a little smaller than a dime, raised, crusty, and has hair over it. What is the best thing to do? Cut it off and treat with scarlet oil? That is what is generally done around here, is there another way as well?
