we have 2 adult Nigerian does that came to us with horns and they were too big to be disbudded by burning off, same goes for the 2 nubian doelings we bought. well, we decided to band the horns with little green cheerios that we normally use for castrating the bucklings. you put the band on the castrater (used to stretch the rubber band) and put it as low as you can at the base of the horns ( we also shaved the head at the base of the horns) tape em on (remove tape after a few days the tape keeps the bands from rolling) in about 6weeks, the horns will fall off. minimal blood , minimal discomfort and BAM! horns gone! ill admit its weird to see these does with out horns!
