Ok so I have a goat that I have skinned and boiled to get the meat off the head, but I am struggling to get the damn horns off so I can clean inside them. Everyone says 'boil the head and the horns will just pull off!' Well they are not! I have tried to put them in a vice and twist but still they aren't coming off. Its the most infuriating trophy prep I have ever done and because I cannot really complete the skull by boiling in peroxide until the horns are off the skull is looking a little yellow. Help!!
